Same problem, I don't know what is wrong. Windows will only read the CD or DVD if it is in the drive when it boots. However, Nero and anyother program will read the drive. The error msg is "Windows cannot read from this disk. The disk might be corrupted, or it could be using a format that is not compatible with Windows." I also have this problem with all removable disks such as my digital camera cards. Any ideas on what I can do?
