I have Windows 7 x64 running on an ASUS M50VM. The DVD drive works completely unreliably if not at all.

When I first got the machine it came with Windows XP and I upgraded it to Windows Vista X64 and the DVD drive worked fine.

When Windows 7 RC2 came out I tried it on a Virtual Machine and I liked it so much that I upgraded the machine to Win7 RC1. The DVD drive worked fine.

Of course, RC1 started spontaneously rebooting, so when Windows 7 was released I did a clean install of Windows 7. Just to clean install I mean I did a format of the hard drive and installed it from scratch.

Ever since then, the DVD drive mostly doesn't work. I can sometimes read from disk but that will often hang. (Please see my description below of hang for details). CD or DVD writes always fails with a hang (I have done a successful write only one time.)

Here is what I mean by hang:

  • Explorer Window is unresponsive.
  • Any software accessing the DVD drive is unresponsive.
  • The DVD tray will not eject.
  • Using a paper clip will eject but the disk is usually spinning real hard.
  • Attempting to shut down windows will fail. I have waited as long as ten minutes but the whole OS seems to hang. I do a hard shutdown.
  • Sometimes accessing the DVD (when it does not cause a hang) will still fail and the device will actually seem to disappear from the system until I reboot.

A couple of other things. It is not a hardware failure. It is the Windows OS. I know this because I swapped out my DVD drive with a friend with the same model...his machine is fine (he is still running Vista X64) and my machine still fails.

For what it is worth, I swapped out my primary disk with the INTEL 160GB SSD.


Here is what System Information shows about my DVD drive

Any ideas?

For the is the model mentioned for the dvd drive in Device Manager. HL-DT-ST-DVDRAM GSA-T20N ATA Googling that shows problems but none for Windows 7. – Seth Spearman Jul 9 '10 at 0:24

Have you looked for a firmware update for the drive? Is it an OEM drive or a retail drive?

Have you tried this troubleshooter tool?

It is an OEM drive. I have tried the troubleshooter but it finds no problems. Seth – Seth Spearman Jul 9 '10 at 0:25
What make and model PC did the drive come from? Some OEMs provide firmware upgrades. – Moab Jul 9 '10 at 13:37

After long search I found HL-DT-ST-DVDRAM GSA-T20N firmware for Win7:

I hope it will help, because it's really difficult to find these drivers.
