I have a Samsung SD 612 dvd-rom which can no longer play or even explore dvd disks. It still plays ordinary cds okay. I have tried deleting it from device manager (where it is listed as an ordinary cd rom drive - is this normal?), but the problem persists. The only major software change I have made to my system since I noticed the drive wasn't working is to install and then uninstall Internet Explorer 6. I've tried flashing the firmware, also to no avail. The drive is on the secondary IDE channel and set at master, with a cdr drive as the slave. It worked fine up until the last few days. Is this likely to be some kind of Windows problem or is the drive dead? I'm running Win 98, by the way.
