Troubleshooting CD-ROM, DVD, and Floppy Drives
Here are three media devices that are easily replaceable
and relatively inexpensive. Still, sometimes these units will
function adequately while containing errors. CD-ROM and
DVD drives are treated the same when troubleshooting.
Following are common situations and ways to possibly
resolve such errors.
Ask these questions or do these things before replacing a
so-called “bad unit”:
• Check power connectors and cables. If the floppy light
stays on, the cable is probably reversed. Is the CD-ROM
or DVD cable seated and oriented correctly? Are the
jumpers set right, namely as “slave” or “cable select”? Is
it conflicting with the hard drive on the same channel? Is
auto-detect on in BIOS, and is this Plug and Play capable?
• If a disk doesn’t work, does a different one work? If yes,
the problem may be the media. It may also be the result
of an older, slower drive that has a hard time recognizing
less-than-perfect media. In this case, you may want to
upgrade.
• Sometimes using a cleaning kit to eliminate dirt and
dust on the read heads will eliminate minor problems
as well.
• Swap suspect cables with known good ones to find
defective connectors.
• Check that there isn’t a floppy disk in the drive when
booting up; this will result in a nonsystem disk error.
• Multiple drives have to be configured correctly in BIOS.
Maybe you have the floppy drive set as “A” instead of “B,”
or vice versa.
