Yes. This generally means that you have a cabling or termination problem. Timed out in data-out phase usually means that the bus is stuck in a particular phase. Since the error is coming from the da(4) driver, it has probably been stuck in data-out phase for 60 seconds. > I also have a Sony DDS3 external tape drive, which is off at the moment. > Sometimes when I connect the tape to system some strange SCSi errors > appear in the console (I don't have any know, the tape was off in this > boot...). Well, in order to diagnose those errors, we'd have to see what they are. :) > What I'd like to know is what these error messages mean. I don't know > much about SCSI.

You should check for a cabling or termination problem.
