Floppy Drives
Attaching a floppy drive can be done in a similar manner to an IDE drive. See the diagram below
for an example of a floppy cable. Most of the current floppy drives on the market require that the
cable be installed with the colored stripe positioned next to the power connector. In most cases,
there will be a key pin on the cable which will force proper connection of the cable.
Below are some symptoms of incorrectly installed floppy drives. While they are minor and
installing them incorrectly doesn't cause severe problems, it may cause your system to freeze or
crash when trying to read and/or write to diskettes.
Drive is not automatically detected
Drive Fail message at bootup
Drive does not power on
Drive activity light is constantly on

The first floppy drive (commonly denoted as
A:) is usually attached to the end of the cable
with the twist in it. Drive B: is usually connected
to the second or third connector in the cable
(the second or third connector after you install
Drive A:).
Refer to your floppy drive's installation
instructions (if available), or contact your dealer
if you are unsure about how to attach the
floppy drive(s). Remember, you can only have
2 floppy drives connected at any given time.
Usually caused by faulty cables, cables put in
backwards or a bad floppy drive or
motherboard. Try another floppy drive to verify
the problem if the cable is properly installed or
try replacing the actual cable. Also check to
see if the onboard floppy controller is enabled
in the BIOS setup.
The cable, floppy drive or motherboard may be
faulty. Try another drive or cable to verify.
Check power cable and cabling. Maybe a bad
power supply or drive cable problem.
Usually signifies that the cable on the drive is
on backwards, which is a common issue.
Reverse the cable at the floppy drive end and
try again.
