The only problem I've heard of, relating to Newburry drives, was a bootstrap problem where the drive took much longer to become ready after a SCSI reset than expected, and the bootstrap gave up. Since this problem only affected the bootstrap, you should have been able to use the drive for additional storage, or whatever, but just not boot from it. This problem has since been fixed, and I believe was released with 4.21. If you're up to rev, give it a try. The SCSI implementation for the AV 4000 is, for all practical purposes, the same as that on the AV 300. The implication that the AV 300 is somehow flawed is simply not true. We've made a very strong attempt to make sure that as many off-the-shelf SCSI disks would work as possible. However, as anyone who's worked closely with several different SCSI devices will tell you, there's probably a ill-behaved device out there just waiting to strike :-).
