This comes across my screen just as I'm wrestling with why the hell my new drive won't write a complete dump. I had an old IBM/Archive/Seagate DDS-2 drive (identified as Archive, not Python), which had been working great for almost a year. But lately it had been having problems, and I was using two tapes per backup on the NT box. So... I bought a refurbished Scorpion DDS-3 drive. It's awesome. Fast, holds tons on a tape. Only one problem -- it wouldn't write to my old DDS-2 tapes. So Seagate send me a firmware upgrade. Now the drive writes my DDS-2 tapes. Excellent! I only had about $300 worth of those I wanted to continue using. ;-) But now I'm getting these SCB resets/timeouts that everyone else is talking about. What the?! The drive works beautifully under NT. It worked fine the last time I tried it last weekend on NetBSD. But this weekend I wasn't able to get a complete dump with four different tapes (under NetBSD -- got NT backups just fine). The thing that people have been saying is wrong is that the drive identifies itself as being able to support tagged-command-queuing, but not actually supporting it? The thing is, my drive doesn't appear to be advertising such an ability (as far as I can see). It identifies itself as such: ahc0: target 2 synchronous at 10.0MHz, offset = 0xf st0 at scsibus0 targ 2 lun 0: SCSI2 1/sequential removable st0: drive empty So does anyone have an idea what the actual problem is? It would be cool if I could make this dude work. The system is a NetBSD 1.3 box, Adaptec 2940UW (7880), 64MB RAM, etc... ----------------------------------------------------------------------------- Michael L.
