When I cleaned it I took it apart and cleaned the lens with 100% alchol rubbing alchol and a q-tip. I have both verbatim disks and regluar hp lightscribe disks. It just read anything that has to do with dvds. It wont read regular dvd movies, blank dvds, or dvd data disks. It reads blank cds, cd data, and audio cds fine. It will also burn to blank cds but not blank dvds. Everytime i put anytype of dvd in the drive it says there is no disk in the drive.
Im running xp home edition with sp2 if that info is needed.
