I upgraded my hard drive in Lenovo T61P; decided to start fresh with Windows 7 Pro (64-bit). DVD/CD drive working until Windows 7 was installed.

Now the driver is not recognized. Device is HL-DT-ST DVDRAM GSA-U10N ATA Device. It appears on device manager but with the yellow tag; System tells me the driver is corrupted or not recognized. I Ran PC-Doctor and it reported all was OK. Ran ParetoLogic Driver Cure which said the driver was fine.

I went from XP Professional (32-bit) to Windows 7 (64-bit) during this

Uninstall the HL-DT-ST DVDRAM GSA-U10N device in DM, reboot, see if it works now. – Moab Dec 19 '11 at 22:09
