Old WD 2GB works on one IDE channel, not other

I was using an old Intel 430HX type mobo and trying to transfer files
from an old WD-22100 to a newer HD, but the BIOS didn't recognize the
WD drive when it was plugged into the first IDE channel but worked
fine on the second channel. So I thought that the first channel was
bad, but it worked fine with other drives, including a 1.6GB WD. I
tried a different cable (both 40-wire), and the jumpers seemed fine
(set for Master, No Slave and Master With Slave, only one drive per
cable). Voltage meter showed +5.14V and +12.08V (AT PSU, mobo and HD
connectors).

Is there something odd about certain old WD drives that make them act
this way? I think this happened once before with a different mobo.

Shouldn't matter which IDE channel and it should be set for Master with no
slave when it's the only drive on the one channel (cable). Master with
slave when there's a second drive on the same IDE channel (cable).

I.E. If you're putting each drive on a separate channel (cable), as you
seem to describe, BOTH are the Master on their respective IDE channel
(cable) with no slaves and both should be set as master with no slave.

Some (all?) WD drives have an unusual jumpering configuration. They
have "single", "master" and "slave".

What you want is the "single" setting. If you choose "master", the
drive will timeout waiting for a non-existent slave drive to come ready.

So, if I read you correctly, it is working fine on it's own on the second
channel but not on its own on the first, using the same jumper settings in
both cases?

That sentence does not make sense.
Voltage meter showed +5.14V and +12.08V (AT PSU, mobo and HD connectors).

Yes, but not what you described. Although, it not really clear what
you actually describe, especially after that second sentence.

Drives have no idea what channel they are on.
They should act the same on both channels in identical combinations.
You did of course check that all drives are treated identical by the BIOS?

Didja try the 'cable select" mode?

I meant that I tried the WD-22100 with only the MAster jumper
installed, and then I tried it with no jumpers installed (the
recommended setting for master w/o slave present).

The BIOS (Award version 4.51) was set to "AUTO" for every IDE device.

That is odd. I don't see any easy explanation for that.
Sounds like one of those situations where you learn to live with it.
