On Both my cdrom and my dvd, if I have a Disk in the drive and Type DIR & read that disk, then remove the disk. Then put a totally different disk in the same Drive. Then Type dir and Try to read the Drive it will Display the Dir of the CD that I have Just removed. I have to reboot my machine to be able to correctly read the disk. It does the same thing if I use windows explorer also. This is driving me crazy. Why is this happening, better yet - How can I stop this and read my drives correctly?
