It's possible you have one of the over-enthusiastic 1542's; also bring all of the jumper-selectable timings back to the slowest possible settings. > >sd0(aha0:0:0): HARDWARE FAILURE asc: 44,a2, FAILURE > >sd0(aha0:0:0): HARDWARE FAILURE asc: 44,a2, Retries = x > >sd0(aha0:0:0): HARDWARE FAILURE info: 2d18 asc 15,1 Mechanical > >positioning error sks(80,f) > >sd0(aha0:0:0): HARDWARE FAILURE info: 1d70 asc 15,1 Mechanical > >positioning error sks(80,f) > >vm_page : pager input (probably hardware) error, PID 11 failure If you get this consistently, I would still be suspicious of the drive.

You're on the money, it may just be that you don't have enough history with those damned 1542's. If you can, check with Adaptec for details - there was a batch (either B's or C's, I can't recall) that slewed the bus way too hard. One workaround for these is, IIRC, to slow the board down. Adaptec should be able to tell you whether your 1542 is one of the culprits. > Phil > > > > -----------------------------140730798114994776041470031863-- > > -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" -Terry Lambert UNIX: live FreeBSD or die!
