What drives are you using ?

  Are you running with the latest/recommended firmware of the drives ?

  What brand are the cartridges ?

  What library are you using ?

  Do you see any kernel errors ? 

  I usually put the following line into my /etc/syslog.conf so I have all
kernel related issues in a single file:

kern.debug                      /var/adm/kernel

 (and don't forget to kill -HUP the syslogd). 

  Can you send the output of the inquire command ?
