Need help with Hard Drive Jumper settings

Hi, Tom -

Perhaps the links on this page will lead to usable info for you -

IBM sold its drive business to Hitachi, now Hitachi Global storage technology. Your IBM drive is one of this family:

The Quantum drives are more problematic. Quantum sold its drive business to Maxtor. Maxtor was not very good about keeping the Quantum information available. Maxtor sold out to Seagate. Presuming that they mean well, they are incompetent at providing the Quantum documents.

What connector is on that Quantum Viking II? I may have a paper copy of their documentation. I will look for it, but it may take a while. Is there any more info like W, WSE, N, or C after the identification?

Tom,

When deaaling with undocumented drives, I take a different approach. Set the ID on a drive that you have spec sheet information to something other than 0 and assume that the Quantum drive is at ID 0. Then use SCSI Probe for a quick check of the drive IDs.

As Grant mentioned, older Quantum drives are tough to find documentation on so let that be the zero drive. I can also check a stack of old drives and look for clues.

NBMs,

Here are a couple of useful links:

I could have abreviated this link but it has such visual apeal that I did not.

The graphic shows ID 1, ID 2, ID 4. Your labels are for locations 0, 1, 2, 3. No jumper at location 0 = ID 0. A jumper at location 0 = ID 1. A jumper at location 1 = ID 2. You may already know that but for the benefit of others, the label by the pins does not match the ID number.

I would steal a jumper from an old motherboard or CD-ROM drive and leave the HDD jumpers alone. (my 2¢ : ) )

On the Quantum Viking II:

Jumpers on the circuit card labeled TE and TP may be present, but may not do anything on certain drives. If active on your drive, a jumper on TE will enable on-board Single-Ended Termination for Single-Ended drives (not compatible with LVD Termination), and TP will add 5 Volt power to the wires in the cable reserved for it.

SE will force an LVD drive to run as Single-Ended, rather than the usual software control. Not recommended.

On drives with a 20-pin or 12-pin jumper block on the same end as the data cable, the drive should be oriented so that the circuit board is down, metal top plate is up. Then the top right pin is pin 1, and pin 2 is below it, so jumpers are all installed in "up-and-down" orientation.

1-2 for Addr0
3-4 for Addr1
5-6 for Addr2
7-8 for Addr3

On 12-pin connector:
9-10 Enable Termination
11 +5Volts out
12 n.c.

on 20-pin connector:
9-10 force Single-Ended
11-12 LED 11 Neg, 12 pos
13-14 Wait Spin (Don't spin up motor, wait for software command)
15-16 Spin Delay (Delay motor spin up based on SCSI ID)
17-18 Reserved
19-20 Reserved

Which data connector makes a difference. Apparently, there were both SE-only and LVD-capable ((with SE fallback) drives available.
