Don't forget that there are multiple files on the distribution tape, the
Sun documentation gives your the layout - to use non rewinding tapes for
input and output. Then do a "mt -f /dev/devicename rew" when done.
You should try using the high density tape (/dev/nrst8 if cart, /dev/nrmt8
if tape), and a sensible (small) blocking factor. Continue to use "dd".
