I have a DVD/CD-ROM Drive and a CDRW Drive. They both have started to not recognizing that a disk in is the drives, unless I reboot the PC with the disk in the drive. After reboot they see disks and work fine as long as drive is not opened. I am using Win XP Home. The CD/RW drive works fine when you are using a disk writing program to write to the disk, even without rebooting but only in that program. If I open XP in safe mode both drives work as they should. Has anyone else had this problem and are there any suggestions for a fix?
