cable select question

I have an old IBM model 8303 52U desktop computer that has a Western Digital model WD400BB drive installed in it. Probably the drive that originally came with the machine.

The drive is attached to the primary IDE connector on the motherboard.

Why is it that when I switch the jumper on the drive from cable select to MASTER, the drive is not recognized by the computer ? Works fine when jumped as CS.

The cable that is connecting the drive to the motherboard has only ONE device/drive connector on it.

I was under the impression that a cable select cable/ribbon had to have multiple device connectors on it. Is that incorrect ?

The CD-RW is connected to the secondary IDE motherboard connector and is jumped as master and is recognized and works fine.

Is there something quirky about this particular model of Western Digital drive. Seems like to me that I might have read something about that in the past ?

Thanks.
 
the end of the IDE cable is master, the middle of the cable is slave.

in general everyone just uses cable select for ease of use unless you have a device that's so old it fails at CS

Like I said there is NO middle of the cable. The cable has only ONE device connector plug (and, of course the plug/connector for the motherboard, NO middle).

And also, as I said, it is the MASTER setting that the drive will not work on. Works fine when set to CS.

Thanks.

 
After trying it on another cable, it still would not be recognized when jumped as master. But in the process of trying that, I cut a wire in the new cable when trying to get the drive cage back in place (perhaps that is why it did not work).

In any case, when I switched it back to the original cable (and I still had not changed the jumper back to CS, it was still on MASTER), all of a sudden the system recognized the drive with the jumper at master. Perhaps when I first tried it on master, the jumper was not seated correctly or something.

Now for some additional memory and I can get this thing in production.
