CD and DVD rom drives not showing in bios

  Eileanbeag 17:15 24 Sep 09

My friend has a H.P computer running Windows XP. As she inherited it from her son she just restored to Factory Condition; his appeared to work OK until she came to load drivers when it was discovered that both the CD rom and the DVD rom drives were not showing under My Computer and are not showing in bios. I have looked through the Forum helproom and tried a download which was suggested might help (XP_CD-DVD fix) but this did not help. Any suggestions?

MAke sure that in BIOS IDE controllers are Enabled

Thanks - wont see her till next week but will try that

Now checked and they are enabled - can we try anything else? Both drives disappeared at the same time - one while it was actually in use

Its time to open the Box and check the cable is connected fuly at both ends drive and motherboard.

It may also be worth swapping the cable, and even the power plugs.

Thanks - will try that tomorrow and report back

As Fruit Bat as instructed check the power plugs I would also suggest initally only connect the drive that was not being used.

Also ensure that neither drive has a disc go into device manager and remove both drives and reboot

Drives are not showing in Device Manager or Bios - although they used to be

If not showing in BIOS then either

IDE controller not working
Data cable u/s
power cables u/s (psu lost a rail)
or drives u/s (one drive may badly affect the other)
(I have had two drives fail together)
Bad setting of jumpers may cause problem (If failed while one working not this in your case)
mother board failure.

Many thanks - this was motherboard failure. Thanks for your help
