A co-worker accidentally overwrote two files with tiny ones with the
same names. Needless to say, I need the originals. The data can't be
regenerated due to a physical change in the device which produced the
event data. (ok... so non-destructive examinations aren't always
completely non-destructive :^).

The originals are waveform files about 4 MB long and the new files are
about .5 MB.  (Pete Goodeve: I know... it's being fixed - will be using
the ASL filerequester! - BTW, any comments?)

I ran DiskSalv, but I guess the file headers got trashed, since no
duplicate filenames corresponding to the ones I wanted were retrieved.
Each waveform event has a repeatable header that I could recognise if I
saw it.

Question: is there a utility (like the old Diskzap) that can work on an
80 MB partition? If so, can I follow a thread & designate it to be
moved to a new file - fsdb fashion? Or any fashion really? I can even get
by with most of the data. 

re backups: Yes we backup. No, the files weren't on the backup since
they were overwritten about a minute after they were closed :^(

Thanks much,
