Backup - in detail

[Asheville Joe]

I'm trying to do a dump -M -0uf /mnt/portable/root /dev/hda7
to dump my main disk to my auxillary disk.  Dump keeps saying end of 
tape and out of space.  My auxillary disk is supposed to be 120GB - no 
way to run out of space - unless I got my 4GB removable in there by 
accident.   How do I tell?  df doesn't mention /dev/hdb1.
