CD-ROM spins but cannot access drive due to wrong drive letter assigned.

Cause:


The 'Current drive letter assignment' box for the CD-ROM driver and the drive letter of CD-ROM drive in 'My Computer' window do not match.
NOTE: This may have been caused by the recent removal of a drive device that was configured with a real mode driver (such as RAMDRIVE.SYS in CONFIG.SYS) when the CD-ROM drive is a Plug-and-Play device configured with a protected mode driver.

Solution:


Open 'Device Manager', and change the 'Reserved drive letters' for the CD-ROM driver to match the drive letter of the CD-ROM drive displayed in 'My Computer'.
