Dear Sirs,

I am attempting to backup on the above drive with 120m tapes.  When dump
estimates number of tapes for a 9GB disk it suggests ridiculous numbers of
tapes. (My estimate would be just over  2 tapes).  
The command line I used was 

dump 0udf 61000 /dev/nrst0 /filesystem_name

any suggestions for a reasonable density value (or how to make the hardware
compression work on the drive) ???

Cheers,
Carey Nairn
