I've installed windows 98 and 98se to see if it would recognize the drive, which it does, clean installed win xp, it goes through the whole installation, recognizes the drive all the way through to the generic win xp desktop. It shows it in device manager and in windows explorer, try to access the drive and it gives me an invalid drive error, i then go into device manager (after waiting for it to search for devices... longer than usual wait time), and it doesn't show anything on that ide channel. I then connect only the cdrw to the ide 2 channel, and still no go even though it shows in bios and startup screen. Changed cables, no go, changed to different ide channel, no go, reinstalled win 98se all devices show.. could it be a bad device? OH, and i have updated the firmware to the latest (f i believe)... thanks for the responses and help.
