For some reason, when I mount floppy disk (standard HD 3.5" VFAT disk)
it does nothing. No error, just nothing... I have not tried this in
well over a year, but it used to work.
The /dev/fd0 device works normally, I can access it with mtools and
use dd and even access disks in virtual machines running mswindows.
Furthermore, if I make an image of the disk using dd and then loop
mount that image, it works! But when I try to mount my normal
/mnt/floppy fstab entry that I've had for years, or manually "mount -t
vfat /dev/fd0 /mnt/floppy" there is disk activity, but it never shows
up in /proc/mounts and is not mounted for me afterward. If I add "-v"
to mount, it tells me that it mounted, but it didn't actually...
either that or it has unmounted itself instantly before I can see it.
Can anyone else mount floppies? Is there some floppy magic I have
forgotten over the years? Thanks for any tips!

Floppies are normally formatted as FAT12, not VFAT.

Eh. I've seen FAT16 and FAT32 on 1.44MB floppies.
Anyway, Paul should try
file -s /dev/fd0
and
mount -t auto /dev/fd0 /mnt/floppy

Yes, that's what I've tried, and variations of -t auto and -t msdos
and -t vfat. So it was simply not working as expected...
I'm not at home now so I can't test, but I believe I've found the
explanation and probably the answer:
https://bugs.gentoo.org/show_bug.cgi?id=338185
It seems udisks:0 is unmounting my floppy as soon as I've mounted it.
There are various workarounds, ultimately removal of udisks:0 should
make the problem go away, but that is impossible at the moment because
I still have packages which depend on it. It seems Gentoo devs are
actively in the process of trying to eliminate udisks:0 so the problem
won't last forever. Until then there are work-arounds described in the
bug report that I can use.
I will try when I'm at home and provide an update then. Thanks for your help.

Tested at home and it seems this is in fact the cause of my problems.

Paul,
I can't remember the last time I actually mounted a floppy disk. I found "
mtools " to be very usefull for dealing with floppy-disks:
[I] sys-fs/mtools
Available versions: 4.0.13 4.0.15 ~4.0.16 ~4.0.17 {{X}}
Installed versions: 4.0.15(10:46:41 AM 08/02/2012)(-X)
Homepage: http://mtools.linux.lu/
Description: utilities to access MS-DOS disks from Unix without
mounting them
Not sure why it's installed on my desktop as it doesn't actually have a
floppydrive ;)
