Yep, it works. Copying from /dos_d (vfat) to /mnt (vfat) via tar, twice for
good measure. The second one left tar hung and dead. I haven't checked to see
if the vfat fs is trashed, but I expect it's hosed. I'll leave that partition
alone for a couple of days in case someone wants additional info.
I hope these are helpful... but if not, at least they're looooong. ;)
