My computer profile:
Dell DM051
XP Media Center
2992 Mhz Processor
1 Gb Memory
Disk Model Maxtor 6L160M0 160 Gb.
2 CD Drives:
HL-DT-ST DVD+-RW GW4164B
SONY CD-RW CRX320EE

My problem:

No CD drives indicated in "MY Computer".
No CD drives in XP System Information, yet Control Panel Device Manager shows both drives as "working properly".

I have followed instruction for deleting the upper and lower filters from the registry. That changed nothing.

Appreciate any help that works.
