Firstly I changed the ID on my Fujitsu 1Gb drive to 6 and lo and behold it was recognized. The delay after the scsi bus reset is certainly too short. However the data from the drive was frequently garbled. I installed screened scsi cables and experimented with terminators. It works now, but not reliably enough to use. DOS on the same hardware is 100% solid. To my mind this indicates that it is not really a hardware problem in any true sense. My guess is that the scsi driver was written to achieve the ultimate in speed without realizing that it was pushing the hardware close to the edge of unreliability; in some cases beyond it. I am going to install NetBSD on a non-scsi drive and have a close look at that driver. I promise to report back to this group on my findings. Martin Allard --
