I had the same problem. Turns out iTunes was causing the problem. Soon as I uninstalled it, the drive worked.
Unfortunately, I'm still trying to find an answer as to exactly why, but for now, iTunes is out of my laptop.
I have a Dell Inspiron 9300 laptop running Windows XP that is only about 4 months old. The DVD/CD-ROM drive has stopped reading music and game CDs and DVDs. The error message I get says that Windows cannot read the disk because it may be corrupted or using an incompatible format. I don't think thats the case since it has been reading everything before. I have not tried to load any programs and I have reloaded the driver for it. I have cleaned disks and tried several different CDs but none are being read. Will someone please tell me all I have to do is buy one of those lens cleaners for my DVD drive. Thanks.
