I was wondering why I couldn't eject a tape that wasn't open on my new Archive Anaconda. That explains it. Thanks for changing the semantics there, even if I'll have to upgrade to take advantage of it... Anyway, I've got some problems withthis drive, and I've been respectfully informed that FreeBSD-SCSI is the place to bring them up. First of all, I have to do the following sequence (thanks for the help figuring it out!) to load a new tape: Insert the tape. Eject the tape. Insert the tape. Drive spins. Run "mt -f /dev/rst0 fsf 1". Drive spins. Error message. Eject the tape. Insert the tape. FreeBSD 2.0.5, Adaptec 1540B, Archive Anaconda: (aha0:5:0): "ARCHIVE ANCDA 2750 28077 -003" type 1 removable SCSI 2 st0(aha0:5:0): Sequential-Access density code 0x0, drive empty If I skip the various steps I get the following results: First insert and eject: st0(aha0:5:0): NOT READY asc:4,1 st0(aha0:5:0): Logical unit is in process of becoming ready Doesn't matter how long I wait. Don't mt -f /dev/rst0 fsf 1: st0(aha0:5:0): MEDIUM ERROR info:2b4 asc:c,0 Write error st0(aha0:5:0): MEDIUM ERROR asc:c,0 Write error Doesn't matter how often I try, it does this. Don't eject after this: This seems to lock the device. I can't open the device, it says it's busy, but nothing has it open. It's like the SCSI or tape driver is wedged somewhere. Sometimes one of my attempts to open the device after this *will* hang uninterruptably. Also, it recognised DC600 tapes (I put the tape in, do an mt status, and it says it's a QIC-120) but can't read or write them. Possibly I've just got a flakey drive. I'm going to buy an external SCSI enclosure so I can try it on my Bt747, but that can't be until the next paycheck (it's not a total waste of money: I need the enclosure for other stuff), but if the drive's flakey I'd rather not. Input?
