[SDBUG] How to fill my tape to see how many data can i write to him?

[Pedro Moreno]

  Hi people.

     I have 1 tape HP storage-works 232, i want to know how can i write 
data to the tape and see how much data can freebsd write to my tape? Not 
using bacula commands just Unix commands.

     It supposes that supports 200GB, but i have problems with bacula 
and i want to know if is bacula or freebsd. Bacula says that "Tape Full" 
but calculating each client space, i only need 180GB, then why is 
telling me that the tape is full.

     How you could point me how to test my device, thanks all for your 
time!!!

P.S. FreeBSD 6.1-p16 Bacula 1.38.11 MySQL 4.1.
