Fixing broken floppy-diskette support in Ubuntu 11.10

I just had to write a diskette for the first time in a while - I have
to update the BIOS on one of my machines, and DOS is still the easiest
way to do it.

But floppies wouldn't mount.

However, this fixed it:

Didn't even need a restart.

Quoting the article:


Edit “/lib/udev/rules.d/80-udisks.rules” and search for the lines
# PC floppy drives

# USB floppy drives
SUBSYSTEMS==”usb”, ATTRS{bInterfaceClass}==”08″,
ATTRS{bInterfaceSubClass}==”04″, ENV{ID_DRIVE_FLOPPY}=”1″

Replace those “1″ (ones) with “0″ (zeros). That’s all the magic.
Now restart the udev daemon by typing “invoke-rc.d udev restart”

You’re done. It should work now.
