I don't know if this is true for you, but my problem went away when I used SCSI SELECT to reduce the speed for my IBM DGHS09U from 40Mbps to 20Mbps. I suspect cabling issues at this point, as my SCSI cable chain is probably at about the length limit for 40Mbps operation. As to why it worked before my upgrade, perhaps the new driver is faster than the old one! :-) --Elgin On Mon, Nov 08, 1999 at 09:27:38PM -0500, Elgin Lee wrote: > Hmm -- I wonder if the IBM DGHS18V is behaving poorly with the latest > driver.
