i have a LG GSA H20N ATA DVD RW. im using windows 7 RC. and it worked fine for some time after installing the x64 OS, but suddenly from now the CD/DVD is not being read. Whenever i put a CD/DVD into the drive, the light blinks for sometime and goes blank. When i double click the drive in Comptuter, it says insert disk into the drive and opens the tray. The drive is being detected in the BIOS. Anyone with solutions? Oz PS: Tried the Driver Fix, its perfect. deleted the UpperFilter and restarted, but my drive was already shown and detected and worked for the last one week. USING BUILD 7100 RC.
