Question about tape capacity on SS1 using dump/restore

Tue May 29 00:16:52 AEST 1990

I'm working on a SS1 with an external streamer on the SCSI bus. The
streamer uses the 1/4inch cartridges. On normal use, these carttridges are
able to store app. 150 MBytes. For two weeks I've been using the dump
command to backup my disks.  Unfortunately the "dump"-commands put only 40
MBytes on every tape.

Can anybody help me to put more on the tapes ?
