LTD-48246S and LTD-166S not recognized by Win2K



I have an Asus A7V8X mb with an Athlon 2100+. A little while ago, Win2k all of a sudden stopped recognizing my drives. Windows will only recognize them if I boot up with drives in their trays. Otherwise, I get a “Please insert a disc into drive” prompt when I try to access a disc. Also, I noticed that even if I did not boot up with cd’s in the drives, Nero will let me copy a cd from one drive to the other, but I can’t navigate the CD.

Event viewer shows the following:
"RSM cannot manage library CdRom1. It encountered an unspecified error. This can be caused by a number of problems including, but not limited to, database corruption, failure communicating with the library, or insufficient system resources. "

Any advice would be appreciated. Thanks in advance
