I’m a college student in a computer and network administration course. However, my teacher and I are stumped by this. I’m running Windows Svr-2003 on a Dell Optiplex GX270. My working hard drive/primary master is in a 5″-bay removable sled. I recently had to re-image it because of a project that went awry. After the re-imaging, Windows was unable to recognize my IDE CD-RW/DVD-ROM drive, which is the primary slave. The BIOS recognizes it fine, it’s just Windows that can’t see it, not even in device manager. Please help!
