STEP FIVE - Reinstall your internal Iomega CD-RW ATAPI drive as the only device on the secondary IDE channel
If your internal Iomega CD-RW ATAPI drive is connected to the primary IDE channel as a slave, you may want to reinstall your Iomega CD-RW ATAPI drive as the only device on the secondary IDE channel as a master.
- Remove the Iomega CD-RW ATAPI drive from the computer's drive bay.
Warning: Before you remove the computer's case or touch the computer's internal components always turn off the computer and disconnect the computer's power supply and discharge personal static electricity by touching a grounded metal object such as a metal screw attached to the computer casing. If you do not discharge personal static electricity, you risk damage to your hardware and possible loss of data.
Caution: Before you remove your computer cover, check your computer manufacturer's warranty information. Removing your computer cover may void your manufacturer's warranty agreement.
- Close all open applications.
- Shut down Windows and turn off your computer.
- Disconnect your computer's power supply from the electrical outlet.
- Remove your computer's cover.
Note: You may need to refer to your computer manual for complete instructions.
- Remove the mounting screws securing your Iomega CD-RW drive.
- Disconnect the 40-pin interface cable from the back of your Iomega CD-RW drive.
Note: If you have questions concerning which IDE channel your Iomega CD-RW drive is currently connected to or how to identify the secondary IDE channel, please refer to the 'Understanding IDE/ATAPI Connections' section of your Iomega CD-RW manual.
- Disconnect the internal computer power supply from the back of your Iomega CD-RW drive.
- Slide your Iomega CD-RW drive out of your computer's drive bay.
- Change the jumper setting on your Iomega CD-RW ATAPI drive to a master setting.
When you connect your Iomega CD-RW drive as the only device on the secondary IDE channel, you will need to change the jumper setting on your drive from a slave to a master setting. Please use the following steps.
- Remove the jumper (plastic piece) from the back of your Iomega CD-RW drive.
- Place the jumper over the two pins on the right as shown in the illustration below.

- Place your Iomega CD-RW ATAPI drive into the drive bay and connect the interface cable and power supply.
- Slide your Iomega CD-RW drive into an open drive bay.
- Locate your computer's secondary IDE channel.
- Locate the PIN 1 connection on the secondary IDE channel.
- Connect the 40-pin interface cable that came with your Iomega CD-RW drive to the secondary IDE channel. Align the stripe on the interface cable with the PIN 1 connection on the IDE channel.

- Connect the other end of the 40-pin interface cable to the back of your Iomega CD-RW drive.
- Reconnect the internal computer power supply to your Iomega CD-RW drive.
- Secure your Iomega CD-RW drive to the drive bay with the mounting screws.

N If you are still unable to format your CD, please continue to the next step.
STEP SIX - Verify your system is configured for optimal performance
- Right-click the My Computer icon.
- Click Properties.
- Click the Performance tab.

What do I do next?
- If Windows 98/95 is running properly, the Performance tab states 'Your system is configured for optimal performance'. If your system is configured at optimal performance, as shown in the illustration above, please visit the Iomega Contact page at http://www.iomega.com/europe/support/english/en_contact.html to obtain technical support contact options.
- If Windows is running DOS drivers, the Performance tab states 'Windows is running in real-mode'. If your system is running in real-mode, continue with the next step.
STEP SEVEN - Locate and disable any conflicting real-mode drivers
- Click Start and Run.
- Next to Open, type sysedit and click OK.
Note: This will launch the System Configuration Editor and several windows will appear on your computer's desktop.
- Locate the AUTOEXEC.BAT window, which is normally the first window that appears. Scroll down to find any lines that begin with DEVICE=. An example would be DEVICE=MYDRIVER.SYS
- Type REM (for remark) in front of each device line. For example: REM DEVICE=MYDRIVER.SYS If there are no device lines, proceed to step F.
Note: Typing REM in front of a device line will cause the computer to ignore that line when starting up. This may cause some devices not to work properly. REM statements may be removed after testing.
- Mark each device line and save the changes when prompted.
- Close the AUTOEXEC.BAT window and click the CONFIG.SYS window, which is normally the next open window. Scroll down to find any lines that begin with DEVICE=
- Type REM in front of each device line. If there are no device lines, proceed to step I.
Note: A REM will cause the computer to ignore that device line when starting up. This may cause some devices not to work properly. REM statements maybe removed after testing.
- Mark each device line and save the changes when prompted.
- Close the CONFIG.SYS window and the System Configuration Editor.
- Restart your computer.
- Try to format your CD.
- If you are able to format your CD, there is a conflicting real-mode driver. Continue with the next step.
- If you are unable to format your CD, go back into the System Configuration Editor and remove the REM statements. Please visit the Iomega Contact page at http://www.iomega.com/europe/support/english/en_contact.html to obtain technical support contact options.
STEP EIGHT - Resolve the conflict with the real-mode drivers
- Click Start and Run.
- Next to Open, type sysedit.
- Remove one REM statement from the first DEVICE= line and save the changes.
- Restart your computer for the changes to take effect.
- Try to reformat your CD.
If the format does not fail, then continue to use steps A-E above until the problem recurs. Once the problem recurs, the last REM statement removed indicates the conflicting driver.
To resolve the conflict, leave the REM statement on the conflicting driver's device line or contact the computer or device manufacturer to see if they have an updated driver.
If you are still unable to format your CD after obtaining an updated driver, please visit the Iomega Contact page at http://www.iomega.com/europe/support/english/en_contact.html to obtain technical support contact options.
