I'm having some problems with the btape fill test on a Dell Powervault 122T.
I'm running Debian Sarge, with bacula version 1.36.2-2sarge1 and kernel
2.6.18-3 on a Dell Poweredge 2850. The scsi controller is an Adaptec 3960D
Ultra160 SCSI adapter.
All the hardware is new or previously unused.
The btape test command completes without error, and the autochanger test also
works fine. But the fill command gives an error after a while.

I'm a bit lost, as I'm new to tapedrives on linux. Any pointers on where to
start looking for solutions? I've followed the "testing your tape drive"
chapter in the manual, without getting anything useful out of it. Also the
volume capacity looks a bit low before the test fails...
