NT_Worker 0 Posted February 25, 2002 I have a system that has been running XP Professional for a while now. I have an older SCSI 4x/4x/20x CD/RW drive, as well as a 32x SCSI CD-ROM Drive. Two days ago, the CD-ROM drive letters disappeared, and I have no access to them. They show up in the SCSI adapter's BIOS scan, and also in the device manager. I thought I might have a strange termination issue (even though Everything has been setup this way, without change, since Win98, Win2000, and WinXP... 3+ years) I installed an IDE DVD drive, which has worked in the past. The same thing happens, it shows up the device manager (and BIOS) but it does not get assigned a drive letter. I configured a Win98 boot disk, and loaded the appropriate drivers. The drives load, and are functional. I tried a repair, with no effect. This is a fairly fresh install. I ran a clean install single boot WinXP Pro on a freshly formatted hardisk, about one month ago. I had been running it in dual boot with WinXP/Win98SE. System Specs: Pentium III 750 448MB RAM 20GB IDE Boot drive, formatted with FAT32 Geforce 2 GTS 32MB SBLive Value TekRam DC390/F (Ultra-Wide SCSI adapter) SCSI CD-ROMs mentioned above This PC is not internet capable, and not on a network. I attempted a system restore, but received a message warning that drive F: (CD Burner) had been changed, and was not a part of the system restore. That's not a quote, though.
