I reinstalled Windows 7 (x64) because DVD drive stoped being recognized. At first it worked, I even got to burn a dvd. Some time later it misteriously dissapeared again. This question has been asked and answered many times on the Internet, but no proposed solution works for me. Please help! Any clues are gratefuly accepted! EDIT: I booted a live CD and succesfuly tried to burn a DVD. When I rebooted back to windows 7 the DVD drive was there. I burnt another DVD and it also works... I don't know how much it's gonna last... The drive is a TSSTcorp CDDVDW TS-L632H. FW Revision: HS02. It's parallel ATA.
