Depends on wich part of the code is stored out of the bootsector. If
there is only the starterroutine there, then of course the virus can
be executed, but I doubt it will when you rewrite the bs via FDISK.

Indeed there are empty sectors (but I can't image what they are for).
But in my opinnion it would be silly to put viral code there. Since the
most common way of spreading bootsectorviri is via floppy and as far as
I can see floppys (or is this floppies ?) don't have these "empty"
sectors. So the virus would still need a routine to hide itself in data
area.

? Sorry I don't get it : pun in your name
