Using Jaz^®Disks

Use only genuine 2GB* or 1GB* Jaz^® disks with your Jaz Internal SCSI drive. This section describes some of the things you can do with Jaz disks. The help files in IomegaWare^™ software include additional information on using Jaz disks.

Handling Jaz^® Disks

Always store Jaz^® disks in their protective cases when they are not inserted in the drive. Always remove the disk from the drive before moving the computer.

CAUTION! To prevent permanent damage or data loss, never open the door on the Jaz^® disk or drop it.

Jaz^® Disk Compatibility

The Jaz^® 2GB drive can read and write 2GB and 1GB Jaz disks, however, it is optimized for use with the 2GB disks. Reading from and writing to a 1GB Jaz disk are features provided for backward compatibility in using existing cartridges. Because of the differences in technology between the Jaz 2GB and Jaz 1GB drives, drive performance will be reduced when using 1GB Jaz disks.

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

CAUTION! 2GB Jaz^® disks cannot be used in the Jaz 1GB drive. The Jaz 1GB drive will not physically accept a 2GB disk.

Backing Up with Jaz^® Disks

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

The easiest way to back up important data files stored on your hard drive is to use standard copying procedures. On a Mac, you can drag-and-drop files from any folder on your Desktop to the Jaz drive. In Windows you can use My Computer or Windows Explorer to select files or folders from your hard drive and drag-and-drop them to your Jaz drive. One advantage of copying files directly to your Jaz drive is that you can access them easily any time you need them without having to run a restore procedure.

*2GB or 1GB where 1GB = 1 billion bytes. The capacity reported by your operating system may differ, depending on the operating system and reporting utility.

Copying Jaz^® Disks

The simplest way to copy your Jaz^® disks is with Iomega's Copy Machine application. Copy Machine will duplicate Jaz disks using a single Jaz drive. See help in the IomegaWare software for instructions on how to use Copy Machine.

NOTE: Copy Machine cannot copy any files that are open or in use at the time the copy is made. If you do not want to use Copy Machine, you can duplicate a Jaz^® disk by following these steps:

1. Copy the contents of your Jaz^® disk to a folder on your computer's hard drive.



2. Eject your Jaz^® disk.



3. Insert a new Jaz^® disk.



4. Copy your files from the hard drive onto the new Jaz^® disk.

CAUTION! When copying Jaz^® disks on a PC system, do not use the Microsoft CopyDisk utility that is available when you right mouse click on the Jaz drive icon under Windows 95/98, or the DOS program diskcopy.exe, which is included with Windows 95/98. These utilities only work correctly with floppy drives.

Installing Applications to Jaz^® Disks

If you are using Mac OS, just run the install for the application and select the Jaz^® disk as the target for installation. On a PC, some applications and games will only install to, or run from, a fixed disk. In order to install these programs to a Jaz disk, use the Make Nonremovable feature in IomegaWare software to make the Jaz disk appear as a fixed disk to the system. After the software installation is complete, use the Make Removable feature to restore disk to removability.

NOTE: You may need to use the Make Nonremovable feature whenever you run an application from your Jaz disk. Also, whenever the Jaz disk is set to Nonremovable, you will not be able to remove the disk until you reset Nonremovable to Removable or reboot your system.

Read/Write Protecting Jaz^® Disks

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

• Write Protect a disk through 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.

Setting Jaz^® Disk Protection under Mac OS

1. Insert the disk you want to protect into your Jaz^® drive.



2. Open the IomegaWare folder on your Mac hard disk, then open the Tools folder and double click the Tools icon.



3. In the main Tools window, click on the icon for the disk you want to protect (or unprotect).



4. Select the Disk Protection tool.



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

Setting Jaz^® Disk Protection under Windows

1. Insert the disk you want to protect into your Jaz^® drive.




Open My Computer and right click on the Jaz^® drive icon.



2. Select Protect or Unprotect from the drive shortcut menu.
   
   
3. Choose the protection option you want to use. Click the Help button if you need information on any of the options.




NOTE: Although Jaz^® disk protection options are set and removed using IomegaWare^™ software, the actual protection mechanism is secured in the drive hardware. This means the disk protection cannot be bypassed using other software programs.

Formatting Jaz^® Disks

Jaz^® disks are available preformatted. You can format your Jaz disks to quickly erase all of the files on the disk, change the format type, 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 contains information you want to keep!

Formatting Jaz^® Disks for Mac OS Users

1. Insert the disk you want to format into your Jaz^® drive.



2. Open the IomegaWare folder on your Mac hard disk, then open the Tools folder and double click the Tools icon.



3. In the main Tools window, click on the icon for the disk you want to erase.



4. Select the Erase Disk tool.



5. Choose Short Erase if you want to erase all data on a disk so you can reuse it; choose Long Erase* if you are formatting a disk where you have forgotten the password. Use either option to change the format type from PC to Mac.



6. Click Erase to start formatting the Jaz^® disk.

Formatting Jaz^® Disks for Windows PC Users

1. Insert the disk you want to format into your Jaz^® drive.



2. Right click on the Jaz^® drive icon in Windows Explorer or My Computer.



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 Jaz^® disk.




*Only the Short Format option can be used when formatting a 1GB Jaz disk in a 2GB Jaz drive.

Using Jaz^® Disks Cross-Platform

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

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

On Mac OS Systems

• You can use PC-formatted disks on a Mac OS system that has File Exchange 3.0 or higher or PC Exchange version 2.0 or higher installed. It is recommended that you use PC-formatted Jaz^® 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 IomegaWare^™ software on a Mac OS system to erase the disk.



• Click on the Iomega Software Manual (located inside the IomegaWare folder on your Mac hard disk) to read additional information on using PC-formatted Jaz^® disks with File Exchange or PC Exchange (and other DOS-mounting utilities).

On Windows PC Systems

• PC systems cannot read a Mac-formatted Jaz^® disk unless special software is installed on the system. If you try to use a Mac-formatted Jaz 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.

Transferring Files Between Mac and PC

If you need to transfer files between a Mac and PC, you can use a PC-formatted Jaz^® disk if File Exchange 3.0 or higher or PC Exchange version 2.0 or higher is loaded on the Mac. You can use a Mac-formatted Jaz disk if the PC has disk exchange software installed.

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