Under xp pro - sp3, the two optical disks suddenly became unavailable on a friend's pc. They are recognized by the system but both have an exclamation mark in the the Device Manager.

There is no virus (checked that). I intend to do the following:

1. uninstall the devices and reboot

2. If that doesn't work, I'll try a repair-install.

Is there anything else I can try?

One of these may help:
1. Uninstall the drive through Device Manager.
Restart computer. The drive will be automatically reinstalled.
or...
2. http://support.microsoft.com/kb/314060
Restart computer.
or...
3. Download, and run Restore Missing CD Drive patch
Double click on cdgone.zip to unzip it.
Right click on cdgone.reg, click Merge.
Accept registry merge.
Restart computer.
or...
4. Go to Device Manager, click a "+" sign next to IDE ATA/ATAPI Controllers.
You'll see two items:
- ATA Channel0 (or Primary Channel)
- ATA Channel1 (or Secondary Channel)
Right click on each of them, and click Uninstall. Confirm.
Restart Windows. They'll be automatically reinstalled.

Thanks for the tips which I'll be trying out tomorrow.

Concerning your item 2, I had a look in my own registry (no problem, everything working fine under XP): there is no LowerFilters entry, just the Upper. Odd, isn't it.

Sometimes, just one type of filters is listed. Remove it anyway.
