Flexible Disk Drive Problems

Symptoms:
•
There are lost clusters

There are read/write errors
•
The HP Server will not start from a diskette
If you cannot boot from, write to, or format the flexible disk, do the following:
1. Review the Troubleshooting Checklist and read about Boot Device Priority before you
continue.
2. Try booting from a good known flexible disk.
3. Check to see if boot from the flexible disk drive is enabled and if there is a bootable diskette in
the flexible disk drive.
4. Select the Setup Utility (press [F2] during the boot process and check that the HP Server's
mass storage configuration is correct. If for some reason you cannot run the Setup, you can
clear CMOS and reconfigure the server.
Try to reboot.
5. If you cannot format or write to a flexible disk:
Ensure diskette is not write protected.

Ensure disk drive is properly configured with the Setup utility. Make sure that "Start from
◊ ◊ ◊ ◊
Flexible Disk" option is disabled.
6. Verfiy all internal drive cables are securely attached and functional. Inspect the cables and
reseat the connectors at both ends.
7. If the cables are securely attached, and the drive still does not work, replace the cables with
known good cables, one at a time.
8. If the problem persists, and/or there is an error code, replace the faulty part (the drive, the
system board, etc.)
9. If the problem persists, check for environmental problems that can damage disk media and disk
drive heads.
Environmental problems result from:
Radiated Interference: Sources include communications and radar installations (such as at

an airport), radio/TV broadcast transmitters, and hand-held receivers.
