UNIX is a multi-user, multi-processing, timesharing system; consequently,
if you mistakenly remove the last link to a file (does Norton give you
links?), the data blocks having been reclaimed by the system are likely
to have been overwritten by other processes before you have time to take
remedial action.

Also note that UNIX implements inter-user access protection, so a random
user cannot access the raw disk as would be required to fiddle around
like most such utility packages.

Sure.  On UNIX you can easily implement any number of solutions to the
accidental deletion "problem" (if it seems to be a problem for you).

The very aspects of UNIX which make raw disk diddlers infeasible are
among the features that make it powerful.
