Yeah, but that's nothing compared to the HP-UX 9 box we have that reboots
when you put a Sun 4mm into it's drive and try to read it :)

It's too bad there isn't a portable way to get the block size of a tape
drive, and/or a tape itself... or just to ask what kind of drive a given
device corresponds to...
