Appendix B. Problem solving
Computer problems can be caused by hardware, software, or human error. Using the information in this
section, you might be able to solve problems yourself or gather helpful information to pass on to a
service technician. You might also need to refer to your computer, operating system, or sound-adapter
documentation.
Review the following list for any problem descriptions that might fit your situation.
v Your computer or drive does not operate correctly, or the busy indicator light does not turn on.
Take the following actions:
1. Check that the disc is label side up in the drive.
2. Check that all devices are properly connected to the computer and to an electrical outlet.
3. Turn off the computer, unplug the cables for your computer and all attached devices, and remove
the computer cover.
4. Check that all power and SATA cables are securely attached. Disconnect the SATA cable and check
it for bent or misaligned pins. If you do not find any, reconnect the cable.
5. Replace the computer cover, and reattach all cables and power cords. Turn on the computer, restart
the operating system, and press the Open/Close button. If the tray fails to open and the busy
indicator does not light, turn off the computer and try using another 15-pin dc power cable.
v You cannot access the drive, or the DVD-RAM (CD-ROM) icon is not displayed.
When the drive is properly installed a DVD-RAM or CD-ROM icon is displayed in the My Computer
window. Double-click My Computer. If a CD-ROM icon is not present in the window that opens,
verify that the drive has been properly installed. Restart your computer. If a drive icon is still not
found, continue with the following steps:
1. Click Start .
2. Select Settings .
3. Select Control Panel .
4. Click System .
5. Click the Device Manager tab.
6. Double-click View Devices by Type .
7. Select IDE ATA/ATAPI Controllers from the list displayed in the Device Manager window. Verify
that there are no conflicts with the controller. The device status indicates whether the controller is
working properly.
8. Select DVD/CD-ROM from the list that is displayed in the Device Manager window. Verify that a
CD-ROM device is present in the list and that no conflicts exist. The device status indicates
whether the device is working properly.
9. Click OK .
10. Close all windows and restart the computer.
If the device icon is still not present, check cable connections and resolve any conflicts that might exist.
v The drive is not recognized by the operating system, or the drive performs erratically.
Some computers have Compatible and High Performance modes for mass storage devices. Normally,
the drive functions better under the High Performance mode. However, if your drive is not functioning
properly in that mode, you might need to use the Compatible mode.
Use the following procedure to check the configuration-setup information for your computer.
1. Access your configuration utility program.
2. Select Devices .
3. Scroll down to the Mass Storage Devices section.
