From Max's original message he seems to have actually reformatted the
drive, which is much more serious than simply deleting files. Actually,
when you delete a file in the normal way it isn't deleted at all; rather,
the OS simply flags the space that the file takes up as being available
to be overwritten (normally a file's space is protected from being
overwritten so that when you save file B it isn't saved over the top of
file A -- unless it has the same name, of course). So deleted files
actually aren't deleted until the OS uses that space for a new file.
Formatting, on the other hand, DOES wipe data. However, as the FBI and
other security agencies know very well, whilst a single reformat will
render the data on a drive Totally Gone to the average user, with the
right tools it *can* be recovered. I read once that it takes 7 reformats
of a drive to completely destroy the data on it to the point where it is
*really* unrecoverable (guys may want to bear that in mind when erasing
those girly pics before giving their girlfriend their old mac). So the
low-down is that a reformat is not the end of the line but you'll need  a
specialist service to have even a hope of recoving the data. I think.

Hope this helps;
Rick
