[Bug 36846] Re: The filesystem type of a volume is identified incorrectly.

[rinnan]

Same problem here and same situation.  It causes "pmount-hal" to fail
which causes automounting to fail on my USB drive, which had once been
formatted VFAT but is now formatted, on the same partition, ext3.  Is
there a way to "fix" the formatting so that hal won't be confused
anymore?  There must be some VFAT "residue" left over after the change
in file system type.  I suppose I could back the partition up, blank the
whole drive (there's only one partition) with /dev/zero and dd, then
repartition, reformat, and then restore, but does anyone know a less
drastic solution?
