Floppy Drive Problems
During the power-on
self-test (POST), the
computer checks the floppy
drive, comparing its
characteristics with the
system configuration
information. (The light
blinks as the computer
performs this check on a
floppy drive.)
Basic Checks:
l 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
"
Help Overview " for instructions on obtaining technical assistance from Dell.
l When you turn on the computer, you can hear floppy or hard-disk drive activity during the boot routine. If your
computer does not boot, call Dell for technical assistance. (See "
Help Overview " for instructions.) Otherwise,
see the " Dell Diagnostics ."
l Test this indicator by inserting a floppy disk into the drive, typing dir a: at an MS-DOS prompt, and pressing
.
l Ensure that the floppy disk is not write-protected if you are trying to copy data to it.
l Run the Diskette tests as described in " Dell Diagnostics ."
l Try a different floppy disk in the drive. If the new floppy disk works, the original one may be defective.
l Check the settings on the Page One submenu of the system setup program .
l Clean the drive using a commercially available cleaning kit.
NOTICE: Do not attempt to clean drive heads with a swab. You may accidentally misalign the heads,
rendering the drive inoperable.
If the problem still exists after you complete the basic checks, fill out the Diagnostics Checklist as you perform the
following steps:
1. Save and close any open files, exit any open application programs, and shut down the computer.
2. Remove the floppy drive from the
modular bay .
