I ran into something I hadn’t yet seen firsthand today. A PC (running Windows XP home) with 2 optical drives (CD-RW and DVD drive). However, neither cd drive showed up in My Computer and both of them had a yellow exclamation point in the device manager listing. Of course, two drives don’t just go bad at the same time, so I wondered if it might be the Secondary IDE connector on the system board or the cable that was causing the trouble. In retrospect, I might could have assumed that they wouldn’t show at all if that were the case, but I checked against a usb connector and good cd drive just to be sure that we could rule out hardware as the problem. So, then it came time to see if the driver was the problem.
