I'm assuming that the code 000 is the audio tape code; that's what my audio tapes have. The 60m tape I have is also about 5 years old, and may not have the correct coding. But that's only part of the problem: both these tapes work perfectly on the same hardware with BSD/386, so if it needs to be disabled, BSD/386 knows how to do it. I'll have a look through the code. Do we have any SCSI bus trace facility? Greg
