Getting Started

Here's how to get started using your Zip 250 SCSI drive:

1. Unpack the Zip drive and accessories.




1. Solutions CD (includes IomegaWare software and the User's Manual) 2. Zip 250 Drive Quick Install Guide 3. SCSI Data Cable 4. Power Supply 5. Zip 250 SCSI Drive

NOTE: You will need to purchase a Zip disk to use your Zip drive (no Zip disks are included in this package). Use only genuine Zip disks. Other disks will damage your drive. The Zip 250 drive features backward compatibility that enables you to read and write to 100MB Zip disks. However, because of the higher capacity of the Zip 250 drive, performance when writing to a 100MB Zip disk is significantly reduced.

2. Install the IomegaWare software.
NOTE: You must install IomegaWare software first! Installing IomegaWare software installs the drivers your computer needs to support the Zip drive. If the necessary drivers are not installed, the Zip drive might not be recognized or might not work correctly.
3. Connect your Zip SCSI drive.

*100MB or 250MB capacity where 1MB = 1 million bytes. The capacity reported by your operating system may vary.

Connecting Your Zip 250 SCSI Drive

The instructions in this section show how to connect your Zip drive to the built-in 25-pin SCSI port on a Mac^® or Mac-compatible computer.

G3 and G4 Users

To connect your Zip drive, you will need to first install a SCSI PCI Card. Contact your local reseller to purchase one.

PowerBook Users

If your PowerBook supports SCSI, you will need a special PowerBook cable (which you may already have) or an HID-SCSI adapter to connect the Zip drive to a PowerBook. If you do not have a Powerbook SCSI cable, you need to contact your local reseller.

iMac^™ Users

The iMac^™ computer does not have a PCI slot for a SCSI card. You need to purchase a Zip USB drive rather than a Zip SCSI drive to use your Zip disks.

| top of page |

1. If you have not already installed IomegaWare software, install it now.

2. Check the SCSI IDs and termination settings of existing devices.

   Go to step 3 if there are no other SCSI devices connected to your computer. If there are other devices connected verify the following:

   • SCSI ID 5 is not being used by those devices
   • Termination is set properly for all SCSI devices
   Instructions on how to check the SCSI ID and set the termination reside in the SCSI Guidelines. If another SCSI device is connected to your computer, complete steps 1-5 in the SCSI Guidelines section, before continuing to step 3.
   
   
3. Locate the necessary SCSI cable.
   
   If you are connecting to a 25-pin connector, continue with step 4. If you are connecting the Zip drive to a device that does not have 25-pin connector, you will need to purchase a different cable or connector. See the illustrated chart of available SCSI connectors and adapters that can be used to help connect your Zip drive. Before continuing with the next step, determine which cable may be needed in connecting your Zip drive. If you need to purchase a different cable, connector, or adapter, see Purchasing Iomega Products for more information.



4. Shut down your Mac^®, turn off all connected devices, and disconnect all electrical power.

CAUTION! Always turn off power to the computer and all devices connected to it (such as printers or drives) before beginning any computer hardware change.

5. Connect the end of the data cable marked "zip" to the Zip connector on the back of your Zip drive.

If the connector does not go on easily, try turning it over. Tighten all connector screws.

CAUTION! Never move the drive while a disk is inserted.

| top of page |

6. Connect the other end of the SCSI data cable to the 25-pin SCSI connection on your computer.








NOTE: If you are connecting your Zip drive to an existing SCSI chain, make sure the SCSI ID and termination are set correctly see Connecting Your Zip Drive to a SCSI Chain.






CAUTION: If you choose to connect your Zip drive to a Fast SCSI-2 or Ultra SCSI card rather than to a Mac standard SCSI connection, make sure that the Zip drive is always located at the end of the chain. The Zip does not operate at Fast SCSI or Ultra SCSI speeds but it should not slow the performance of other devices if it is connected at the end of the chain.

| top of page |

7. Connect the external power supply and turn on the power switch.
   
   

   

   
   Check that the green activity light on the Zip drive flashes briefly. The green activity light on the Zip drive flashes as the disk spins up, or when it is busy, and glows steadily while it acquires data. When the light goes out, the drive is ready to use. If the green activity light does not flash, refer to Troubleshooting.

   

1. Power/Eject Button with Green Activity Light




CAUTION! Use only an approved Iomega Zip power supply. Other power supplies may damage your Zip drive.

8. Restart your computer.


9. Insert a Zip disk and the Zip drive is ready to use. You should see the Zip disk (or drive) icon on your desktop.
   
   If the appropriate icon does not appear, see the Iomega Web Support Site at http://www.iomega.com/support or refer to the Troubleshooting on the User's Manual CD.

Connecting Your Zip Drive to a PC

The instructions in this section show you how to connect your Zip drive to a SCSI card that has been installed in your PC.

• If you plan to use an Iomega SCSI card such as the Zip Zoom PCI SCSI Card, see Purchasing Iomega Products.


• If you plan to use a non-Iomega SCSI card, refer to Non-Iomega SCSI Cards in the "SCSI Guidelines."

1. If you have not already installed the IomegaWare software, install it now.


2. Check that your PC has a SCSI card installed.





SCSI Adapter (installed inside the computer) Back of computer SCSI Connector (from SCSI adapter)




Your PC must have a SCSI card installed. If your computer does not already have a SCSI card installed, one will have to be installed. Purchase a Zip Zoom SCSI card (see Purchasing Iomega Products) and follow the included instructions to install it.

If you choose to connect the Zip drive using an alternative method, the following instructions in this section will not apply. See the documentation that shipped with the adapter for instructions on connecting it to your Zip drive and PC.

Windows NT^® 4.0 users—you will need to install driver software for the new SCSI adapter. Refer to Troubleshooting for more information.

3. Check the SCSI IDs and termination settings of existing devices.

   Go to step 4 if there are no other SCSI devices connected to your computer. If there are other devices connected verify the following:

   • SCSI ID 5 is not being used by those devices
   • Termination is set properly for all SCSI devices
   Instructions on how to check the SCSI ID and set the termination reside in the SCSI Guidelines. If another SCSI device is connected to your computer, complete steps 1-5 in the SCSI Guidelines section, before continuing to step 4.

4. Shut down your PC, turn off all connected devices, and disconnect all electrical power.




CAUTION! Always turn off power to the computer and all devices connected to it (such as printers or drives) before beginning any computer hardware change.




| top of page |



5. Connect the end of the data cable marked "zip" to the Zip connector on the back of your Zip drive. If the connector does not seem to fit, try turning over. Tighten all connector screws




CAUTION! Never move the drive while a disk is inserted.



6. Connect the other end of the data cable to the SCSI connection on your computer.




You will need a different cable or a cable converter only if you are connecting the Zip drive to a SCSI device that does not have a 25-pin connector. See the necessary SCSI cable and converter chart for the available types of cables and connectors for the Zip drive.



IMPORTANT: Make sure you connect the Zip cable to a SCSI connector and NOT to a parallel (printer) port. The parallel port is the same size and shape as some of SCSI adapter connectors, but the parallel port will not support this model of the Zip drive.

NOTE: If you are connecting your Zip drive to an existing SCSI chain, make sure the SCSI ID and termination are set correctly.










CAUTION: If you choose to connect your Zip drive to a Fast SCSI-2 or Ultra SCSI card rather than to a Zip Zoom PCI SCSI connection, make sure that the Zip drive is always located at the end of the chain. The Zip does not operate at Fast SCSI or Ultra SCSI speeds but it should not slow the performance of other devices if it is connected at the end of the chain.

| top of page |



7. Connect the external power supply and turn on the power switch.





8. Check that the green activity light on the Zip drive flashes briefly. The green activity light on the Zip drive flashes as the disk spins up, or when it is busy, and glows steadily while it acquires. When the light goes out, the drive is ready to use. If the green activity light does not flash, refer to Troubleshooting.

Using Your Zip Drive

To use the Zip drive, insert a Zip disk, then select the Zip drive letter or disk icon on your computer. You can store and copy files to and from the Zip drive using the same methods you use for other drives on your system. If you need instructions on how to copy files, refer to the help files for your operating system.

| top of page |

Inserting Zip Disks

Always turn on power to the computer before inserting a Zip disk. When you insert a Zip disk, the green activity light will flash momentarily and go out. If the light continues to blink slowly, push the disk eject button to eject the Zip disk, then reinsert it.

| top of page |

Ejecting Zip Disks

Mac^® OS Systems: Select the Zip disk icon and use Put Away from the File menu, or drag the disk icon to the Trash icon.

Windows^® 95/98/Me systems: Push the disk eject button or use the IomegaWare^™ software eject command. This command is available when you right click on the drive icon in My Computer or Windows Explorer.

Windows NT^® 4.0 and Windows 2000^® systems: Use the IomegaWare software eject command.

CAUTION! To avoid damage to your Zip drive or Zip disk, always remove the disk when it is not in use or before disconnecting or moving your Zip drive.

Disk Eject in Case of Power Loss

The computer must be powered on for normal disk insertion and removal. If you need to eject a Zip disk during a power failure, access the rear of the Zip drive and push a straightened paper clip into the eject hole which is located just above the power connector (see illustration below).

CAUTION! Disconnect power from the computer before using the emergency disk eject hole. Do not try to forcibly remove a Zip disk from the drive. If the disk does not eject immediately, repeat the emergency disk eject procedure as described above.

| top of page |

Drive Sleep

The Zip SCSI drive has an automatic sleep mode that spins down a Zip disk after 15 minutes of inactivity. This feature minimizes power consumption when the Zip drive is not being accessed. The Zip disk automatically spins up again when the drive is accessed.

Compatibility with 100MB Zip Disks

The Zip 250 drive features backward compatibility that allows you to read and write to 100MB* Zip disks. Because of the higher capacity of the Zip 250 drive, however, performance when writing to a 100MB Zip disk is significantly reduced. This means that a large file that takes 10 seconds to write to a 250MB* Zip disk could take about 90 seconds to write to a 100MB Zip disk (using your Zip 250 SCSI drive to write both disks).

To maximize performance of your Zip 250 drive, you should use 250MB Zip disks whenever you want to store new information. If you have existing data on 100MB disks, you can transfer it to 250MB Zip disks using the Iomega Copy Disk tool. See Copying Zip Disks.

Here are some important things to know about using 250MB and 100MB Zip disks and drives together:

• If the Zip 250 drive appears to hang when you are writing to a 100MB Zip disk, you can verify that the drive is operating correctly by checking that the green activity light is blinking irregularly. (A slow, steady blink may indicate a problem with the drive. If there is a slow, steady blink, try pushing the disk eject button to eject the disk, then reinserting the disk.)

• You can use the Short Format option if you need to format a 100MB Zip disk in a Zip 250 drive; the Long Format option is not supported for 100MB Zip disks in the Zip 250 drive.

• A 250MB Zip disk cannot be used in a Zip 100 drive; the Zip 100 drive will automatically reject a 250MB disk.

If you encounter any problems using 100MB Zip disks in your Zip 250 drive, contact Iomega Technical Support.

*250MB capacity where 1MB = 1 million bytes. The capacity reported by your operating system may vary.

* 250MB and 100MB where 1MB=1 million bytes. The capacity reported by your operating system may vary.

Backing Up with Zip Disks

It's important to always keep current backups of your valuable data—whether the primary data is stored on your hard drive or Zip disks! You can use Zip disks to back up both. (See Copying Zip Disks for information on how to make backup copies of your Zip disks.)

The easiest way to back up important data files stored on your hard drive is to use your system's standard procedures to copy them to your Zip drive. For example, if your operating system is Windows^® 95/98/Me, you can use My Computer or Windows Explorer to select files or folders from your hard drive and drag-and-drop them on your Zip drive. One advantage of copying files directly to your Zip drive is that you can access them easily any time you need them without having to run a restore procedure.

| top of page |

Copying Zip Disks

The simplest way to copy your Zip disks is with the Iomega^® Copy Disk tool. This tool will duplicate Zip disks using a single Zip drive.

Mac^® OS Users

See the help files installed with IomegaWare software on your Mac hard disk for instructions on copying your Iomega disks.

Instructions for Windows^® PC Users

1. Insert the disk you want to copy into your Zip drive.


2. Right mouse click on the Zip drive icon in My Computer or Windows Explorer.


3. Select Copy Disk from the drive shortcut menu.


4. Select the drive and directory you want to copy information to and from.

   NOTE: CopyDisk erases any files on the target disk if the capacity of the source disk is the same as the capacity of the target disk. CopyDisk adds a folder to the target disk if the capacity of the source disk is smaller than the capacity of the target disk.

5. Click the Start button.

NOTE: The Iomega Copy Disk tool cannot copy any files that are open or in use at the time the copy is made.

If you do not want to use the Iomega Copy Disk tool, you can duplicate a Zip disk by following these steps:

1. Copy the contents of your Zip disk to a folder on your computer's hard drive (C:).


2. Eject your Z ip disk.


3. Insert a new Zip disk.


4. Copy your files from the hard drive onto the new Zip disk.

Formatting Zip Disks

Zip disks are available preformatted. You can format your Zip disks to quickly erase all of the files on the disk, change the format type (PC or Mac^®), or to repair a disk that has developed bad sectors.

CAUTION! Formatting a disk erases all data on the disk. Do not format any disk that con tains in fo . .you want to keep!

To Format Zip Disks:

1. Insert the disk you want to format into your Zip drive.


2. Right click on the Zip drive icon in My Computer or Windows Explorer.


3. Select Format from the drive shortcut menu.


4. Choose the format type:
   • Use Short Format if you want to quickly erase all data on a disk so you can reuse it.
   • Use Long Format* if you are formatting a disk where you have forgotten the password, or if you need to repair a disk that has developed read/write errors due to bad sectors.
   • Use either option to change the format type from Mac^® to PC.


5. Click Start to start formatting the Zip disk.

*Only the Short Format option can be used when formatting a 100MB Zip disk in a Zip 250 drive.

Read / Write Protecting Zip Disks

IomegaWare software includes a special read/write protect feature that allows you to:

• Write Protect a disk through the software instead of with a mechanical write protect switch.


• Write Protect a disk and assign a password so that no one can add, edit, or delete files without entering the password first.


• Read/Write Protect a disk so that it cannot be read from, or written to, unless the user enters the password you assign. If you use this feature, make sure your IomegaWare software is open and running.

To Set Zip Disk Protection on a Windows PC:

1. Insert the disk you want to protect into your Zip drive.


2. Right mouse click on the Zip drive icon in My Computer or Windows Explorer.


3. Select Protect from the drive shortcut menu.


4. Choose the protection option you want to use. Click the Help button if you need information on any of the options.

To Set Zip Disk Protection on a Mac:

1. Insert the disk you want to protect into your Zip drive.


2. Open Iomega Tools and click on the Write/Protect icon.


3. Choose the protection option you want to use. Click the ? (help) button if you need information on any of the options.

NOTE: Although Zip disk protection options are set and removed using IomegaWare software, the actual protection mechanism is secured in the Zip drive hardware. This means the disk protection cannot be by-passed using other software programs.

Using Zip Disks Cross-Platform

Mac OS and Windows PC systems use different disk formats. If you use your Zip drive on both PC and Mac systems, here are some important points you need to know:

On Mac OS Systems

• You can use PC-formatted disks on a Mac OS system that has File Exchange 3.0 or higher installed. It is recommended that you use PC-formatted Zip disks for file transfer only. You may lose file resource information if files you use on a Mac OS system are stored on a PC-formatted disk.


• You can change a PC-formatted disk to a Mac-formatted disk by using the Iomega Tools application on a Mac OS system to erase the disk.

CAUTION! Formatting a disk erases all data on the disk. Do not format any disk that contains information you want to keep!

| top of page |

On PC Systems

• PC systems cannot read a Mac-formatted Zip disk unless special software is installed on the system. If you try to use a Mac-formatted Zip disk on a PC that does not have disk exchange software installed, you will see a message indicating that the disk is not formatted.


• You can change a Mac-formatted disk to a PC-formatted disk by using IomegaWare software on a PC to erase the disk. (Observe the CAUTION above!)

Transferring Files Between PC and Mac

If you need to transfer files between a PC and a Mac, you can use a PC-formatted Zip disk if File Exchange 3.0 or higher is loaded on the Mac. You can use a Mac-formatted Zip disk if the PC has disk exchange software installed.

NOTE: The Zip drive does not convert file formats. When using files cross-platform, the file format and application must work on both PC and Mac platforms.

Handling Zip Disks

Always store Zip disks in their protective cases when they are not inserted in your Zip drive. Avoid exposing your Zip disks to direct sunlight, extreme temperatures, moisture, or magnetic fields (such as from monitors or speakers).

SCSI Guidelines

Connecting Your Zip Drive to a SCSI Chain

SCSI (pronounced SKUH-zee) is an acronym for the Small Computer System Interface—an industry standard for connecting peripherals to most personal computers. The SCSI interface allows you to connect a series of devices to a single SCSI connection by cabling them one to another, forming a SCSI chain. Defined here in the "SCSI Guidelines" is how to connect more than one SCSI device to the same SCSI connection (either built-in or from a SCSI card). A SCSI card is the device that plugs into your motherboard and to which SCSI devices are connected.

SCSI Chain

A SCSI chain is a series of SCSI devices, both internal and external, cabled together on a single SCSI connection. For a SCSI chain using Ultra SCSI, it is recommended that the total length of all cables in the SCSI chain both internal and external should not exceed 1.5 meters (~5 feet).

CAUTION! To avoid damage to your hardware, always turn off power to all devices in the SCSI chain before making any change to the SCSI configuration.

| top of page |

1. Before installing your Zip drive, check the SCSI IDs of your existing devices.

The SCSI ID is an address number, ranging from 0 to 7, which is assigned to each SCSI device. Each device in a SCSI chain must have a different SCSI ID number and ID 7 should not be used for any device. It is usually reserved for use by the SCSI host adapter card. The following is an illustration of how a SCSI chain may be configured. Your configuration may be different.



SCSI ID 3 SCSI ID 2 SCSI ID 4 SCSI ID 5 SCSI ID 7 (SCSI Card; The adapter card is usually a device in the chain)




| top of page |




NOTE: Each device in the SCSI chain must have a different SCSI ID.

You can usually check the SCSI ID on the device itself. It is normally the number setting on the back of the drive. A Zip drive is typically set at the factory to SCSI ID 5. Refer to the information that came with that drive for instructions on setting the SCSI ID.

If you are not able to see the SCSI ID assigned to each of the devices in the chain externally, you may be able to use these steps to find them on your computer:

Mac^® Computers

If you have Mac^® OS 7.6 or higher, you can use the Apple^® System Profiler to check the IDs of the devices in the SCSI chain.

1. Go to the Apple^® Menu and select the Apple System Profiler.
2. Depending on your version of Apple^® System Profiler (see the illustrations below, as a example), you will need to either select Device Information under the Select menu, or click on the Devices and Volumes tab.







| top of page |




NOTE: If Apple^® System Profiler lists more than one SCSI bus, you will need to select the correct one for your Zip drive. SCSI bus 0 is generally the internal (hard drive's) SCSI bus, and SCSI bus 1 is the external. If you are connecting to a SCSI card such as the Zip SCSI card, it may appear as a bus number other than 0 or 1.

3. If there is another device on SCSI ID 5, you will need to change the SCSI ID of your Zip drive. See step 2 below for instructions on changing the SCSI ID of your Zip drive. If you do not need to change the SCSI ID, continue with step 3 below.

   CAUTION! If you change the SCSI ID of another device in the SCSI chain, do not set it to 0 or 7. The SCSI controller card and the internal hard disk use SCSI ID numbers, by default they are set at 0 or 7.




| top of page |




Windows^® 95/98/Me PC Compatible Computers

You can use the Device Manager to check the IDs of the devices in the SCSI chain.

1. Start your computer.


2. Go to the Start menu. Select Settings and then Control Panel.


3. Double click on System, and then click on Device Manager.



| top of page |








4. Double click on Disk Drives in the list of devices shown.
5. Click on the first SCSI drive shown under Disk Drives to highlight it, and then select Properties.
6. Select the Settings tab and note the Target ID. This Target ID is the SCSI ID that the device is using. If there is no Target ID, it is not a SCSI device.

 









| top of page |

• Close the current window for the first drive and repeat steps E and F for the remaining drives under Disk Drives. Once you have completed this for all of the drives, locate any other SCSI devices in the device manager and repeat steps E and F for each device.

  NOTE: To locate the SCSI ID for other SCSI devices, refer to the manufacturer's documentation.

• If there is another device on SCSI ID 5, you will need to change the SCSI ID of your Zip drive. See step 2 below for instructions on changing the SCSI ID of your Zip drive. If you do not need to change the SCSI ID, continue with step 3 below.

2. Set the SCSI ID on your Zip drive.

If another device in the SCSI chain is using SCSI ID 5, you can change the ID on your Zip drive using the following procedure:

• Verify that the power to your Zip drive is off.

• Set the SCSI ID to 6 by moving the SCSI ID switch on the back of the Zip drive to the up position.

NOTE: The Zip drive has only two possible SCSI IDs: 5 or 6. If another SCSI device is using SCSI ID 6, you must change the device SCSI ID to another setting.






1. SCSI ID Switch: upper position is 6; lower position is 5

| top of page |



3. Set the termination in your SCSI chain.




SCSI termination is the method in which data is sent through a SCSI chain. The data signal is constantly sent from one termination point in the SCSI chain to the other. If one side is not terminated properly, or too many devices are terminated, the SCSI chain may not work correctly.

NOTE: SCSI guidelines require that the two ends of the SCSI chain have termination ON. Make sure also that the devices in between the two ends are NOT terminated. The SCSI adapter, or SCSI card, is also considered a device.






Last drive in internal SCSI chain is terminated. Middle chain is not terminated. Middle chain is not terminated. Last drive in external SCSI chain is terminated. SCSI adapter is not terminated.




CAUTION! Data loss can occur if SCSI termination is not set properly.

If your Zip 250 SCSI is the last device on the chain, set the termination switch in the upper or ON position.






1. SCSI termination switch (1=ON; 0=OFF)




Other devices may have switches similar to the Zip drive or may use a termination block similar to the one shown below. Refer to the documentation that came with that drive for information on proper termination.









1. Termination block



4. Locate the necessary SCSI cable or converter.

You will need a different cable or a cable converter if you are connecting the Zip drive to a device that does not have 25 pin D-Sub connector. To purchase Zip cables, converters and accessories, see Purchasing Iomega Products. The illustrated chart below shows some of the common types of SCSI connectors. If the device that you are connecting to has a:

	25 Pin D Sub Connector—The SCSI Zip drive and the Zip Zoom SCSI card use this connector. This connector works directly with the Zip SCSI data cable or any standard 25 pin SCSI cable. If you need an extra Zip SCSI data cable, see Purchasing Iomega Products.
	50 Pin High Density Connector—Iomega Jaz® drives and Jaz Jet SCSI adapters use this connector. Use a 50HD to 25 D-sub SCSI cable to connect your Zip drive. To purchase this cable, see Purchasing Iomega Products.
	50 Pin Centronix Connector—Some older SCSI adapter cards and drives use this connector. To connect your Zip drive to this connector, use a 25 pin D Sub SCSI female to a 50 pin Centronix male cable converter with a Zip data cable. To purchase a Zip 25-50 pin cable converter, see Purchasing Iomega Products.




| top of page |




CAUTION Always make sure you connect your Zip 250 SCSI drive to a SCSI connector and not to a parallel port (printer port). The Zip SCSI cable fits on the parallel port, but the Zip SCSI drive will not work on a parallel port. If you connect the Zip SCSI drive directly to a parallel port, it may damage the drive or the computer.

5. Connect the SCSI cable from the Zip drive to your existing SCSI chain.

   Connect the cable coming from the left SCSI port in the back of the Zip drive to the computer or to the previous SCSI device in the SCSI chain. If you are connecting another device to the Zip drive, follow the cable from this device and connect it to the right port on your Zip drive. You may need an adapter to fit the 25 Pin D-Sub connector on the Zip drive.

   CAUTION! When connecting the Zip drive with other SCSI drives make sure the SCSI ID and termination on your Zip drive are set correctly.

   Your Zip drive is a high performance drive that will work with most PC/Mac^® SCSI cards (i.e. Zip Zoom PCI SCSI card or Mac standard built-in SCSI connection). The typical data transfer speed is 10MB per second.

   Ultra SCSI Performance

   Ultra is a Fast SCSI-3 specification capable of 20MB per second transfers. If you choose to install a PCI Ultra SCSI card instead of a Mac standard or a Zip Zoom card, you must connect your Zip drive at the end of the chain. The Zip drive does not operate at Fast SCSI or Ultra SCSI speeds but it should not slow the performance of other devices if it is connected at the end of the chain.

   For example, if you want to connect a Jaz 2GB external drive and a Zip 250 SCSI in a SCSI chain, configure the adapter BIOS so that the Zip 250 is set to non-Ultra SCSI performance (10 MB per second). Then turn off your computer, connect the Jaz drive in the SCSI chain, connect the Zip drive, set SCSI termination, and reboot.

   NOTE: When connecting your Zip drive to an Ultra SCSI chain, you must use only shorter, premium-quality data cables for all drives connected. It is recommended that the total length of all cables in the SCSI chain both internal and external should not exceed 1.5 meters (~5 feet).

   Non-Iomega SCSI Cards

   If you are using a non-Iomega SCSI card to connect your Zip drive on a PC, the card must have a compatible 32-bit miniport driver for Windows^® 95/98. If you are not sure that your card is 100 percent compatible, check with the dealer where you purchased the card or the card manufacturer. You can also check the Iomega Web site for information on compatible cards for the Zip drive. Go to the Iomega web site at http://www.iomega.com:

   1. Click Support.

   2. Go to the Ask Iomega section at the bottom of the page and type compatible SCSI cards and click the Ask button.

   3. A query of questions will be loaded. Click the Ask button next to the question that asks what SCSI adapters and/or cards are compatible with your drive.

   Make sure the necessary software for the adapter is correctly installed on your system before installing the Zip drive.

The Zip drive is not assigned a drive letter (icon does not appear on the desktop).

This could be due to a hardware installation problem or to a resource or software conflict on your computer system. The following suggestions will help you check your installation:

WindowsZip 95/98/Me and Windows NT^®/2000 Users

1. Turn off your computer and disconnect power from the Zip drive. Turn on the computer first, then immediately connect the Zip power supply (or use a power strip to turn on both at the same time). Make sure the green activity light in the center of the power/eject button is on.


2. Make sure you are using the data cable that came with the Zip drive.


3. Make sure none of the pins on the Zip data connector are bent and that the data cable is connected as shown in Connecting Your Zip Drive.


4. Make sure the cable connections are straight and on all the way. Tighten all connector screws firmly and evenly, both on the connection to the Zip drive and to the computer.


5. Make sure the Zip drive is connected to a SCSI connection on the computer. (Use a Zip Zoom PCI SCSI adapter (card) that is installed inside the computer). This model of the Zip drive will not work if it is connected to a serial or a parallel (printer) port.


6. Try reinstalling IomegaWare software. If IomegaWare software is already installed, remove it using Add/Remove Programs in the control panel, restart Windows^®, then reinstall the IomegaWare software.


7. Try changing the SCSI mode on your computer. (See the documentation that came with your computer for instructions.) If the computer still doesn't recognize the Zip drive, the SCSI card on the computer may not be compatible with the Zip drive. Try installing the Zip drive on a different computer. If a different computer recognizes the Zip drive, the problem may possibly be an incompatible SCSI card. To solve this problem you need to add a new SCSI card to your computer.* If neither computer recognizes the Zip drive, refer to How to Get Help.

Installing IomegaWare should automatically install the Iomega Zip SCSI driver needed to support the Zip SCSI drive. If the Zip SCSI drive is not assigned a drive letter under Windows NT^® 4.0, try manually installing the driver by using the following steps:

NOTE: You must have administrator privileges for your local computer in order to install the Iomega software or the Zip SCSI driver under Windows NT^®.

1. Click Start, Settings, and then click Control Panel.


2. Double click SCSI Adapters.


3. Select the Drivers tab and click the Add button.


4. Select Additional Models.


5. Select the Iomega Zip SCSI driver from the list of adapters.

   NOTE: If the Iomega Zip SCSI driver is not listed under Other Adapters, try reinstalling the IomegaWare software.



6. Click Next to continue, then click OK for Windows NT^® to install the necessary adapter driver on your system.


7. Click OK to exit.


8. Reboot your system for the new driver to take effect.

Windows^® 2000 Users

Computer does not start up properly after installing the Zip drive. Computer hangs on reboot or does not operate correctly.

Some computers will not start or operate correctly if a device connected to the SCSI receives power before the computer is turned on. Try the following:

1. Turn off your computer and disconnect power from the Zip drive.

2. Turn on the computer first, then immediately connect the Zip power supply (or use a power strip to turn on both your computer and your Zip drive at the same time).

3. Press the power/eject button on the front of the Zip drive and check that the green activity light comes on.

If the computer still does not start correctly, the problem is probably due to a resource or software conflict on your computer system. Disconnect the Zip drive from the computer and restart.

If the computer does not restart:

1. Make sure that all SCSI connections are on all the way.

2. Tighten all connector screws firmly and evenly, both on the connection to the Zip drive and to the computer

3. Make sure that each device in the SCSI chain has a unique SCSI ID number (no duplicates) and that the SCSI chain is correctly terminated.

If the computer still does not restart:

You want to use Windows^® 95/98 DOS mode with your Zip drive.

NOTE: This section describes how to switch in and out of the MS-DOS mode which is a start option for Windows^® 95/98. It does not apply to the DOS box (or window) that opens when you double click the MS-DOS Prompt icon within Windows 95/98. Use of the DOS box with the Zip drive works the same as it does with any other drive under Windows 95/98.

If you want to use Windows^® 95/98 DOS mode with your Zip drive, copy the DOS drivers folder from your IomegaWare software on the Solutions CD to your hard drive. Right click on the CD icon and select Explore. Double click on the Drivers folder and drag the DOS folder to a new folder on your hard drive.

CAUTION! Do not put the Windows^® 95/98 DOS mode drivers in your autoexec.bat file. This will cause Windows 95/98 to run in real mode, which will result in a significant decrease in system performance.

In order for the Zip drive to operate properly in Windows^® 95/98 DOS mode, you must perform a clean reboot when switching to or from DOS mode. Do not use the option on the Windows 95/98 Shut Down menu that reads: "Restart the computer in MS-DOS mode." This option does not fully support the Zip drive.

To switch to DOS mode:

1. Restart the computer and press F8 just before the full-color Windows^® logo screen loads. (If you are using Windows 95, look for the text line "Starting Windows 95" to appear on the screen. If you are using Windows 98, watch for a black screen with a blinking cursor.)


2. When the menu appears, select Command Prompt Only


3. After the system boots into DOS mode, run guest.exe from the location on your hard disk where you copied the DOS drivers folder.

This procedure will provide access to any Iomega drives on the system. To return to the Windows^® 95/98 graphical interface again, restart the computer.

NOTE: Do not type win at the DOS prompt after running guest.exe; this causes duplicate drive letters.

Disk automatically ejects when inserted into the Zip drive.

Make sure you are using a genuine 250MB Zip disk or a genuine 100MB Zip disk. If you attempt to insert a non-Zip disk into the Zip drive, the drive automatically rejects the disk.

Extension Conflicts (Mac Users Only)

What is an Extension Conflict?

An extension is a software application or driver used to enhance the operating system or access different pieces of hardware on your Macintosh^®. Many of these extensions are used to control hard drives and other types of removable media, including Zip and Jaz^® drives. An extension conflict occurs when an extension is placed in the extensions folder that overwrites the Iomega driver.

Iomega has developed widely compatible extensions for its Zip and Jaz drives; however, some software applications and extensions may not work correctly when used with your Zip or Jaz drive.

IMPORTANT! It is advised that you obtain the latest software release for the extension that is conflicting with the Iomega extension. Software developers often address known conflicts in later versions of their extensions.

Driver Manufacturer World Wide Web Addresses:

If your installation appears to be OK and the problem continues, there may be an extension conflict on your system. Try the following procedure to test for conflicts:

1. Insert a Mac-formatted Zip disk into the Zip drive.
2. Hold down the Shift key and restart your Mac. Make sure you hold down the Shift key until you see the message indicating that extensions are off or disabled.
3. If the Zip disk icon appears on your Desktop, the problem is probably an extension conflict. If you have an extension conflict, try renaming the Iomega Driver by adding three or more spaces at the front of the driver name. This will cause the Iomega Driver to load first and should avoid the conflict. (You will find the Iomega Driver installed in the Extensions folder inside the System folder on your Mac hard disk.) If this solution does not work, refer to the Known Extension Conflicts section below.

Known Extension Conflicts

Listed below are some of the known extensions that conflict with the Iomega extensions. Possible solutions for each are on the following pages.

NOTE:

Control Panels and Extensions are located in your System folder. If you need additional information on disabling them beyond what is provided in this guide, detailed instructions are included in the Macintosh System help file.

*Some versions of Silverlining install the “Silver INIT” and should be disabled when using the Iomega driver.

WARNING Iomega does not support third party drivers. Iomega cannot guarantee the integrity of your data if you use a drive utility extension other than the Iomega driver extension to control your Zip drive.

Solution 1: Remove Non-Iomega Disk Utilities

It is recommended that you remove third-party disk utility drivers from your Extensions Folder. Most disk utility programs will run without their extensions installed.

To Disable Extensions:

1. Select the Apple Menu and then Control Panels.


2. Double click the Extensions Manager icon.

   



3. Find the drive utility extension for the software that is conflicting with the Iomega extension and deselect it. (See table under Known Extension Conflicts)

   



4. Restart your Macintosh.

Solution 2: Disabling DOS Mounter 95™ or Mac-PC Manager

Disable both the extensions and control panels for these disk utilities.

To Disable Control Panels and Extensions:

1. Select the Apple Menu and then Control Panels.


2. Double click the Extensions Manager icon.

   



3. Find the drive utility control panel and extension for the software that is conflicting with the Iomega extension and deselect it. (See table under Known Extension Conflicts page 41.)


4. If DOS Mounter 95™ or Mac-PC Manager moved the PC Exchange extension to a folder on your desktop, place it back in the System extensions folder.


5. Restart your Macintosh.

If you need access to PC formatted disks you can reinstall PC Exchange from your original system disk(s).

Solution 3: FWB Hard Disk Utilities

Use FWB Tool Manager™ to remove FWB control over the SCSI IDs that correspond to your Iomega drive(s). Consult your FWB Hard Disk Toolkit manual for information on setting options for your FWB Tool Manager.

Other Known Conflicts

Power PCs Running System 7.1.2

Upgrade to System 7.5 or greater or download the Iomega Installer version 5.0.3 from the Iomega web site. If you also have a Jaz drive, you should upgrade to System 7.5 or greater.

Connectix RAM Doubler™ 2.0.2

If you are using System 7.5 through 7.6.1, you should remove RAM Doubler from the extensions folder. Mac OS systems released before 7.5, and later systems like System 8.0, do not have conflicts with RAM Doubler.

System 7.5 through 7.6.1 Memory Control Panel

If you are using System 7.5 through 7.6.1, you should turn Virtual Memory off if you are using the Iomega driver. Mac OS systems released before 7.5 and later systems like System 8.0 do not have conflicts with Virtual Memory.

Problems with software dongles or other pass-through devices.

Because there is no single set of SCSI specifications accepted across the industry, there are some SCSI/multi I/O adapters, SCSI peripherals, and software dongles that are not fully compatible with the Zip drive. If you use these devices, it would be best to add another SCSI to your computer.* If you plan to use software dongles on the same SCSI connection as your Zip drive, contact the provider for your dongle before connecting it to make sure you have a device that is compatible with the Zip drive.

*Iomega has approved the use of Warp Nine Engineering's add-on card WarpExpress, which is fully compatible with the Zip drive and will actually improve your drive's performance. Contact Warp Nine Engineering on the World Wide Web at http://www.fapo.com, or call 1-619-292-2748 for sales information.

Problems installing IomegaWare software.

If the IomegaWare software does not install correctly, try reinstalling it.

Using your Zip drive on another computer.

To use your Zip drive on another computer, first install the software. After the software is installed, connect the drive.

CAUTION: This model of Zip drive cannot be used with an iMac^™. Use the Zip USB drive.
