You need to disable tagged queueing and the write-thru cache. The former you can do with camcontrol negogiate 0:3:0 -T disable at every boot (I added a line to /etc/rc.local). Chheck the camcontrol manpage to be sure of the exact designation for your drive. The latter you do through your SCSI BIOS. > > I do not suspect that the drive is losing power and AFAIK (I've checked) > the termination on the drives is fine.
