Cannot use USB floppy drive in Squeeze
I have recently install Debian Squeeze on an IBM ThinkPad X31. It has
an external USB-attached floppy drive. The BIOS sees it. I can boot
from it just fine, and when running Windows 95 in MS-DOS mode (no WIN.EXE
running) I can access it as drive "A:". I used the FORMAT command of
Windows 95 in MS-DOS mode to format a floppy disk (1.44M) without any
trouble.
When Squeeze boots, the following messages from dmesg appear to
be relevant:

(I hope I haven't left out anything pertinent.)
So the floppy drive is recognized as /dev/sdb. I would have
preferred the traditional /dev/fd0, but I can live with that.
I just have to remember that the floppy drive is /dev/sdb.
There was no floppy disk in the diskette drive during boot.
(Otherwise, the BIOS would have attempted to boot from it,
since it is in the boot order ahead of the hard disk.)
At this point, I see the gdm3 login screen, but I do not login;
so GNOME auto-mounting rules are not in effect. I then switch
to text console number 1 via Ctrl+Alt+F1 and insert a freshly
formatted floppy disk, with no files on it, into the diskette
drive. I then see the following:
-----
sd 2:0:0:0: [sdb] 2880 512-byte logical blocks: (1.47 MB/1.40 MiB)
sd 2:0:0:0: [sdb] Assuming drive cache: write through
sd 2:0:0:0: [sdb] Assuming drive cache: write through
sdb:

Then I get many, many iterations of the following set of error
messages before the kernel finally gives up:
-----
sd 2:0:0:0: [sdb] Unhandled sense code
sd 2:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
sd 2:0:0:0: [sdb] Sense Key : Medium Error [current]

sd 2:0:0:0: [sdb] Add. Sense: Address mark not found for data field
sd 2:0:0:0: [sdb] CDB: Read(10): 28 00 00 00 00 00 00 00 08 00 00 00
end_request: I/O error, dev sdb, sector 3
Buffer I/O error on device sdb, logical block 0
-----
My next step was going to be dumping a disk image to it with "dd",
(diskette is R/W) but no I/O to the floppy drive is possible.
The bottom line is that the floppy drive is not usable. What is wrong
here? I did some searching on the internet, and I've seen other
posts with similar error messages, but none of them seem to match
my situation.
