In that case, I suggest that you immediately get a full disk image saved
somewhere safe so that you can play with it at your convenience. In the
*IX world, "dd" will do a raw copy for you. There are also some Win*-
based ones (row-something-or-another). Copies to another large HD or to
CD (can be ISO format, but *IX can also write as ext*, tar, cpio onto
the media).

That's probably true. I'm sure that a Guru or two has had to recover and
decided that it was with a program. Start googling for that.

Another possibility: google for the MBR layout. If your loss was just
the flag (IIRC, x'05') indicating a valid partition got stomped, you
might have an easy out yet. Lots can be done with "dd" and a few good
utils. Even if the flag is lost, you might find partition information in
those first (two) blocks on trk0, cyl0.

HTH and, need I say it, I wish you lots of luck and good backups in the fut=
ure.
