I'm just a newbie, Matt, and I'm sure you will get more qualified
opinions coming your way from people on the list.
A once off cure, long enough to obtain a copy of the drive goes like
this:-
Stick the drive in a freezer for 15 - 30 minutes, reinstall and copy.
I have never done it myself, but on another list some years ago this was
suggested, and it was endorsed by a couple of other list members. There
was an explanation, but I can't remember what it was now.
Save it as a last resort anyway.

David
