Diskette Drive
Problems
During the
power-on self-
test (POST), the
computer checks the
diskette drive,
comparing its
characteristics with the
system configuration
information. (The
diskette-drive access
light blinks as the
computer performs
this check on a
diskette drive.)
Basic Checks:
If you hear an unfamiliar scraping or grinding sound when a drive is accessed,
make sure the sound is not caused by the application program that is running.
The sound could be caused by a hardware malfunction. See "
Getting Help " for
instructions on obtaining technical assistance from Dell.
When you turn on the computer, you can hear diskette or hard-disk drive activity
during the boot routine. If your computer does not boot, call Dell for technical
assistance. (See "
Getting Help " for instructions.) Otherwise, see the " Dell
Diagnostics ."

Ensure that the diskette is not write-protected if you are trying to copy data to it.
Run the
Diskette tests as described in "
Dell Diagnostics ."
Try a different diskette in the drive. If the new diskette works, the original one
may be defective.
Check the settings on the
Page One submenu of the
system setup program .
Clean the drive using a commercially available cleaning kit.
