[ moved to scsi, followup there ] Hard to say. It looks like we're somehow missing early warning and going all the way to end of tape. I've had real trouble reproducing this situation. I've had some reports, but I've not been able to really make it happen for me, and, yes, I use DDS tapes also. Are you in set in fixed block or variable block mode? -matt On Thu, 12 Jul 2001, Jim Bryant wrote: > This is a new issue [was not present in -current a few months ago]. > > Attempting a dump to an HP C1533A DDS-2 drive, dump seems to "freeze the > tape" at EOT. > > Inserting the next volume of the dump and typing "yes" only produces write > errors. > > Performing an `mt rewind`, prior to typing "yes" clears the state, and > allows the dump to continue. > > What's up with this?
