Problems with LG GSA-4163B and 4521B

i have these two stations and neither is recognized by my OS (win xp pro)
it says that the drivers are damaged or missing and now it says that the installationprogram for CD-ROM cant be loaded…does anybody have any solutions?

What does the hardware/device manager say when you check the IDE channels and what is listed about cd/dvd drives?

Have you checked the ide cable(s), jumpers and settings?
