What have I told you about Quantum scsi disks?? :)

Do you have the termination properly set on the SCSI chain?  If you have
two internal drives, then the controller must provide termination on one
end, and the drive on the end of the ribbon cable also needs to provide
termination, and SOMETHING probably has to provide terminator power.
Unfortunately I have no idea how to work with a Sun SCSI controller....
