tapetype w/compression for a HP Ultrium LTO 1 drive

[Salada, Duncan S \(Titan\) @ TITAN]

Hello,

I'm having trouble getting amtapetype to give me a 200gb tapetype for a HP 
Ultrium LTO 1 drive.  It tells me that hardware compression is on, and I've 
tried using "-e200g" with "-f/dev/rmt/0ubn" and "-f/dev/rmt/0cbn" in 
desperation.  But it still will only give me the 100gb tapetype:

define tapetype Ultrium_I-HP_C7145_233S {
    comment "just produced by tapetype prog (hardware compression on)"
    length 100864 mbytes
    filemark 0 kbytes
    speed 14228 kps
}

I'm using amanda-2.4.5p1 on Solaris 10.  I've searched around for a while but 
I've found nothing.  Any hints/explanations would be greatly appreciated.

Duncan
