Hmmm... yes, I'd forgotten about that.  Shouldn't be a problem for most
4mm drives I'm told, but is a problem for many 8mm drives, and of course
most older QIC drives.

At least NetBSD's dump(8) has '-B' and you don't have to jump through
too many silly hoops backwards to specify the size of a tape you know to
be about 2,000,000,000 bytes.....  Now if only tape manufacturers were
more forthcoming with publishing exactly what and how they record things.
