need help with tape backup

[Darryl Cook]

   I need some help with tape backups.  System specs are:

   PowerEdge 2850   running Redhat AS v4.

   Sony Lib/81  AIT-3,  SDX-700V  tape drive.

problem:   Im only getting around 75-85 gb on a tape before it runs
out of room.  It apparently isnt compressing the data.  Im using the
AIT-3  100/250gb tapes so we should see much more than that.  Ive
tried several things including the following:

   dump -j2  and dump -z2 commands but get errors it looks like right
before end of the dump. 

   Error with sense data:sense key Medium Error   and Additional
sense: Cartridge fault.

Ive also tried setting mt -f <device> setblk 0  command but no better
luck.

   Anyone have any experience with this tape drive....suggestions
appreciated.
