CDs Not Dismounting/Mounting

Problem: When one CD is replaced with another, and after the drive has apparently read the CD, explorer does not refresh with the new CD’s volume information but still reports the previous CD’s volume and directory structure. After an erratic number of eject and inserts of the new CD, it may be recognized or a reboot has been necessary. This occurs on both the DVD reader and CD burner erratically.

Environment: Windows XP Pro SP2, Dell Dimension Intel Pentium III @ 863MHz, Samsung DVD-ROM SD-612 and LG CD-RW CED-8080B
