I don't know about other people, but when I write to my Archive Python DAT drive through my Adaptec 2940 on /dev/nrst0 of my 2.2-960801-SNAP system, I am sure to get this: st0(ahc0:4:0): timed out in dataout phase, SCSISIGI = 0x0 st0(ahc0:4:0): BUS DEVICE RESET message queued. Bus Device Reset Message Sent ahc0:A:4: no active SCB for reconnecting target - issuing ABORT SAVED_TCL == 0x40 If I try it again, I get this: panic: ahc0: Timed-out command times out again and then I am history. Everything works fine if I use /dev/rst0, and in fact if I only read/seek through /dev/nrst0 it works fine, and everything else I have put on the bus like hard drives and ZIP drives worked OK. The DAT drive works without a hitch through /dev/nrst0 on my SunOS 4.X SPARC, so I have not bothered to look into it much. Larry
