LVD 160/320 SCSI: termination or dead disk drive?
|

| Hi,
I have the Tekram SCSI controller and a small cable shipped together with
it. The cable is short, absolutely symmetrical and has 2 absolutely same
connectors on both end. No visible terminators.
Also I have a 68-to-80 pin adapter.
Also I have a 80pin drive, which is claimed to be Seagate Cheetan by the
people who sold me it, has the words of "Hewlett-Packard", 73GB and 10.000 rpm
on it. It is identified in INQUIRY data as being Compaq one. The mfg date is at
least year 2004, not older.
Problems:
- on boot, the adapter's BIOS shows INQUIRY data OK, but no CHS values for a
disk
- FreeBSD says "da0: attempt to query device size failed: NOT READY, Logical
unit not ready, cause n". Yes, small Latin "n".
- Windows boots fine, shows the disk in Device Manager, but not in Disk
Management!
- some old Windows command-line disk benchmarking tool I used for years fails
on this disk with "cannot query size" error.
Can this be due to bad termination? Must I switch the jumpers on the drive?
Or is the drive dead completely?

| You'll have to terminate the drive externally. SCA drives don't have
built in termination.

| Thanks, I have solved the problem. The drive was really dead. Putting it in
surely-working machine with surely-working cable and surely-working Adaptec did
not cause anything good. The drive was responding to INQUIRY only, trying to do
low-level format from Adaptec's BIOS failed.
So, I exchanged the drive in the shop.
