Then I would think that dd'ing /dev/zero to the tape would keep it streaming, but it won't. :( > could hte disks be holding the bus for too long? > can you change the "buffer disconnect size" on the disks? Don't know. There is one hard drive, a Fujitsu M1606S (bought from Rod Grimes, so it should be "FreeBSD Certified"), and the only jumpers are for SCSI ID and spindle motor. Is this something that could be set through software? There is also a Toshiba 3501 CD-ROM drive on the bus. I should note, that at one point I had the hard drive alone on the SC200 controller, and the Viper alone on the Adaptec 1542C, and the result was the same: no streaming. I've tried different cables as well. It has also crossed my mind that the tape drive may just be broken, and it is coincidence that it happened right after (or during) a motherboard swap. Anybody know typical failure symptoms for the Archive Viper? I don't get read or write errors, just no streaming. -john
