I've seen several threads here on using the Conner SCSI CTT8000-S based tape drives. Some writers have indicated that they were able to get the HP version of the drives to work, and others had difficulty. I don't believe I saw a final recomendation on how to get these drives working under FreeBSD. If I missed it I appologize in advance. The last entry I saw in my search was the following (in excerpt) From: J Wunsch <j@uriah.heep.sax.de> Subject: Re: BSD Tape Drive Drivers???

I just aquired this drive as a Seagate Tapestor (4 gig native) and I am using an Adaptec 1505 but have also used a 1510. When the system boots it probes with the following result: aic0 at 0x340-0x35f irq 11 on isa aic0 waiting for scsi devices to settle (aic0:2:0): "CONNER CTT8000-S 1.22" type 1 removable SCSI 2 st0(aic0:2:0): Sequential-Access density code 0x45, 512-byte blocks, write-enabled Everything looks pretty good at this point. However, no matter what command I try I get no response from the drive (no light, no activity, etc) and eventually get a "Timed out message". This happens with dump and just about any command, for example: mt rewind st0(aic0:2:0): timed out Since it probes, I'm assuming the driver is the problem although I've checked termination, scsi ID, different cables, no tape on boot and everything else this newbie can determine from the manuals, handbook and these lists, except debug. Are these drives supported under FreeBSD? Is there a patch I need to make to get them to work? Am I being dense and missing the obvious? Any help would be appreciated.
