Well, this doesn't sound like a hardware crash, it's "only" software.
Some program has written garbage on some vital disk areas.

When you get a "Not a DOS disk...", then the "Root block" of that
partition is bad. It's not necessarily totally corrupted, a bad
checksum suffices to evoke this message. You definitely need 
some expert who has deep knowledge of the file system. He should
be able to restore these data. There exist some tool programs
which might help with this job (Fixdisk or DiskSalve (the latter
is only applicable, when you have a *free* partition of at least
the same size available)), but I can't tell details which would
do the job automatically.
