Can't access FAT(32) disks

[Percival P. Cassidy]

I have WinXP SP3 on one machine and find that I am no longer able to
access FAT32-formatted thumb drives or FAT-formatted floppies: I can
read them on other systems, but this machine tells me they are unformatted.

I reformatted a floppy but it still showed as unformatted. chkdsk found
no errors, but the disk still is reported to be unformatted.

RMB -> Properties shows:

File System: RAW

What has happened here?

- Windows XP _______ Edition with Service Pack 3
- What antivirus software?
- What antimalware software?
- Any third party firewalls?
- What changed between the day you last noticed everything was fine and the
first day you noticed everything wasn't fine?

What has happened is that floppies and floppy drives are notoriously
unreliable nowadays. Can't say about your thumb drive.

XP Home

None in operation at the time.

- What changed between the day you last noticed everything was fine and the
first day you noticed everything wasn't fine?

I've so seldom used floppies or FAT32-formatted media on this machine
that a whole lot of changes will have taken place in the meantime.

Further information:

I insert a floppy that has been formatted on another machine.
DIR A: from command prompt reports no recognizable file system.
CHKDSK /F A: reports file system is FAT, no errors found.
DIR A: reports no recognizable file system.
FORMAT A: reports success.
CHKDSK /F A: reports file system is FAT, no errors found.
DIR A: reports no recognizable file system.

Double-click on disk icon in My Computer reports disk is not formatted.
RMB -> Format reports disk cannot be formatted (or perhaps it was format
cannot be completed).
Take disk to another machine; CHKDSK /F A: reports that file system is
FAT, no errors found.
I copy files to that disk on that machine; success.
Bring disk back to the problem computer; DIR A: reports no recognizable
file system.

Google found a reference to this (or a similar) problem at

http://www.updatexp.com/scannow-sfc.html

I copied the i386 folder from the installation CD to C:, made the
recommended changes to the registry, and ran

sfc /scannow

Nothing has changed as far as FAT-formatted media are concerned.
