designation letter is assigned to the drive, double click
desktop. The drive designation is below the drive icon.
As an alternative, open Windows Explorer and scroll down the list of folders until you
locate the drive icon. The drive designation is next to the icon.
The CD-ROM drive is not reading a disc.
!
Check that the disc is inserted in the CD tray with the printed label side up.
Check that the disc is a data disc, not a music disc.
Clean the non-label side of the disc with a soft lint-free cloth, gently rubbing from the
center of the disc to the outer edge of the disc. Or use a commercial CD-ROM disc cleaner.
Try a different CD to see if the problem is limited to one CD.
