Drive suddenly stopped reading any type of dvd. I’ve tried upgrading the firmware to 2.0g, downgrading it back to 1.0d and 1.0f and nothing works. Drive light comes on when i insert a dvd and stays on for a while, then goes off. Tried erasing a dvdrw and keeps telling me that the drive does not contain a eraseable disc…It was working fine a week ago and nothing has been changed on the system since then. I’ve changed the ide cables, tried it in another computer…nothing works cept for cds. Any ideas?
