For some reason I don't completely comprehend, the driver rewinds after each device closure (right term?) even on a no-rewind device for this and some similar hardware. It affects even something as simple as a multifilesystem dump -- each one overwrites the previous due to the intervening rewinds. For similar reasons, Amlabel writes the label, but then it gets overwritten with the first Amanda filesystem dump so amanda thinks it's not an amanda tape. The author of the driver and some affected users have been discussing the best solution for a couple weeks; probably best to join freebsd-scsi to track progress. (I was considering a workaround using "tar" to glob all the filesystems together and write them in one go to the tape -- a gross hack but something that might get me some backups until the problem is resolved. Fortunately I have an old DDS2 drive which behaves well under the 3.x driver). Robert> I've done backups using the QIC-3095 (2gb native) tapes under Robert> FreeBSD 2.2.7. Unfortunately, the use of a larger tape and Robert> newer OS seems to have gotten me in a bind. Actually, it was the driver that changed from 2.2.x to 3.x. They seem to behave very differently.
