It seems if I turn on debugging (levels 1, 2 or 4; 8 doesn't help) for the device (using the scsi command from 1.1.5.1) the forward space file works. Has anyone else with one of these drives seen this? The debug behavior has got me perplexed. I suspect there is a timing problem somewhere but it eludes me. Note that it fails exactly the same on two different systems both running -current and that the Exabyte EXB-8200 tape drives I have on these two systems seem to do just fine. -- Bob Willcox ...!{rutgers|ames}!cs.utexas.edu!uudell!obiwan!bob Austin, TX or try: @uudell.us.dell.com:obiwan!bob 512-258-4224 (home), 512-838-3914 (work) or: obiwan.uucp%bob@uunet.uu.net
