The Graham Utilities and GammaTech Utilities both have HPFS undelete
programs.  It'd actually be a fairly simple task to write one, too, with
all the junk I've stuffed in my head the last couple weeks poking around
HPFS.  The only drawback, compared to FAT, is that it's time-consuming.
With FAT, it's a matter of looking for directory entries that have just had
the first character "deleted".  With HPFS, the drive must be scanned for
FNodes which aren't owned by any files contained in the directory tree.

You don't need to do a low-level format.  If you format with the /L switch,
it'll prevent /F:3 from recovering files from a previous format.  There's
actually a bit in the partition status byte (offset 0x08 in the HPFS
SpareBlock) that says the drive was fast-formatted, so that CHKDSK can
provide the warning it does.
