[Bacula-users] Seagate STT8000A IDE Tape Drive Help

[__DireWolf]

From reading a few of the archives, getting an IDE Tape drive working in bacula is a real nightmare.   Welcome to my Nightmare ;)   Sorry if this looks like too much info but I always see flames about not including enough detail to help troubleshoot.   Anyway, I've started off at the "Testing Your Tape Drive With Bacula" page here: http://bacula.org/dev-manual/Testing_Your_Tape_Drive.html   I first looked for my drive   =============================================== [EMAIL PROTECTED] ~]# dmesg | grep TAPE hdc: Seagate STT8000A, ATAPI TAPE drive ===============================================   Then loaded the ide-scsi driver   =============================================== [EMAIL PROTECTED] ~]# /sbin/modprobe ide-scsi ===============================================   Made sure it worked   =============================================== [EMAIL PROTECTED] ~]# mt -f /dev/nst0 status SCSI 2 tape drive: File number=0, block number=0, partition=0.
