I also just installed an Anaconda tape drive but haven't had any problems like the above. Am running -stable patched thru 0074. Put the tape on ID 6, my 2G Barracuda is on ID 0. Per Richard J Kuhns 's advice I jumped jp6 (documented as "reserved") without ever trying it unjumped. System is a NexGen PCI-90 with Adaptec 2940. What bugs me a little is the tape drive doesn't continuously spool during dump (or tar). Several times it stopped for a second or two. Eventually dump asked me to insert the next tape. No way, 1.35G tape, 500M fs, I aborted. Looks like I've got to teach dump how big the tape is, or figure out how to get dump to run until it reaches the end of tape, or maybe dump was using 512 byte blocks? So for fun I did: "tar -cv /usr /usr1" which is about 1G, and ran to completion. Then used dd to read the tape to /dev/null and got an outrageous data rate reported but a sane byte count. This needs more experimentation. -- David Kelly N4HHE, n4hhe@amsat.org, dkelly@hiwaay.net ============================================================= To invent, you need a good imagination and a pile of junk. - Thomas Edison
