I have 3 computers. One is a Compaq Presario; one is a Gateway; and one is an AOpen. Two of them are running WIN2000, the 3rd WIN98SE. There is at least one CDROM drive in each, and the drives are by different manufacturers.

When I check the system through the Control Panel, there is no indication of any problem with the CDROM drives, There is also no indication of resource conflicts. In general they alll function, and do the things one would expect when they have a CD in them. Nevertheless, I find that I have CDs which will not register as being present with one or two of the computers (not necessarily the same one or two). The CDs range from ones I made using CD_R disks, CD-RW disks, and ones I purchased containing software.

I realize that there are an ENORMOUS number of variables involved in this, and I really don't expect a definitive answer, given the sparse amount of information I' ve provided. I would like to know, though, if anyone has experienced the same kind of problem, and if so if they have found a reason for/solution to the problemIf these are CD's you have burned and they are not showing up the most common cause of this is the burn session was not finalised.

4. Unfortunately, when the drive starts having problems with reading SOME disks, it's one of the signs, the drive may be dying.
