Hi -

	I'm trying to get our 8mm Exabyte drive to function optimally on
a HP/Apollo 400s.  The problem is that using rdump(1) seems to give a lot
less capacity than the rated values for this drive.  Can somebody give me
a clue as to why this is?  The exabyte writes 1K blocks on the tape and
puts an 8K gap when the buffer runs out of data.  Is /etc/rmt somehow
responsible for writing 512 byte blocks to this device?  I'd be very
interested in hearing from people who have seen near-capacity storage
on this type of drive using rdump.

	I'd also entertain suggestions for alternative backup programs.
Rdump provides a very straightforware means for restoring files (as in
restore ivf) and that is why I would like to use it.

		Thanks in advance for all your help,

		Eric Schneider
