	I don't remember if I suggested this here (I did somewhere lately), this
function is one of the few uses I have found for a Mac (and one of those may
be easier to find than an alpha). I needed to do this to get a NeXT disk 
(formated 1024 bytes/sector) onto a Sun (that didn't like 1024 bytes per sector)
If required I can get the name of whatever they used (I believe it was PD).
