I installed a TEAC CD-RW for my sister-in-law a few months ago.She has used it many times w/ no problems.Now she says the CD and the CD-RW don't show up in Device MGR at all.They are still getting power(trays still open and close)It's an IBM 233.I'm going over to trouble shoot it-I'm only going by what she has told me over the phone.I've already had her run scan disk,defrag,reboot it and have windows look for new hardware but nothing so far.She is using WIN98se. I have an extra ide cable -could that have gone bad? I'd love a few tips on where to start w/ the troubleshooting--Thanks Christie
