I tried this and the output was: 8+0 records in 8+0 records out 4096 bytes transferred in 0.036611 secs (111879 bytes/sec) So then I tried my backup script (which is basically a tar command) and got this on the console: (sa0:ahc0:0:6:0): Unexpected busfree in Data-out phase SEQADDR == 0x86 (sa0:ahc0:0:6:0): lost device (sa0:ahc0:0:6:0): failed to write terminating filemark(s) (sa0:ahc0:0:6:0): tape is now frozen- use an OFFLINE, REWIND, or MTEOM command to clear this state. (sa0:ahc0:0:6:0): removing device entry On the ssh terminal / standard output, I got this: tar: Write error: Input/output error Now "camcontrol devlist" doesn't show the tape drive, even though it did before. So I use "camcontrol rescan all" and it comes back. On console, it says: sa0 at ahc0 bus 0 target 6 lun 0 sa0: <QUANTUM DLT-V4 0A00> Removable Sequential Access SCSI-2 device sa0: 160.000MB/s transfers (80.000MHz, offset 96, 16 bit) So then I try: mt -f /dev/sa0 rewind mt: /dev/sa0: Device not configured atlas:jkikpole>camcontrol devlist <SEAGATE ST373207LW 0004> at scbus0 target 0 lun 0 (pass0) <SEAGATE ST373207LW 0004> at scbus0 target 1 lun 0 (pass1) <SEAGATE ST373207LW 0004> at scbus0 target 2 lun 0 (pass2) <LaCie BigDisk Extreme+ 3.AA> at scbus1 target 0 lun 0 (da0,pass3) WTF? Its gone again. On console, I get: (sa0:ahc0:0:6:0): lost device (sa0:ahc0:0:6:0): removing device entry I'm going to tinker some more and see if I can get this drive working again. I'll also try another tape. (Its worth noting that I DID manage to get a tape working thanks to mt -f /dev/sa0 fsf 1 && mt -f /dev/sa0 rewind.) More info later.
