True in cases where the enclosure's bios only recognizes a master. Which is
almost always the case that I've seen. In the case of Western Digital hard
drives, its master alone, or single, jumper selection.

HD>enclosure bios/translation>USB or Firewire bus.

Hello Anna,
Would also add that most, if not all, external HDD enclosures specify that
the HDD should be jumpered as Master regardless of how any other drives
are jumpered.

Factories like CS because they can set all the jumpers the
same, it speeds assembly.

Thanks Jim. Just as I thought.

IF everything can be set to CS AND work quite happily with each other
why have master and slave? They seem to be redundant.

Are there any instances where setting everything to CS does not work?

Thanks.

Bill:
As your instincts apparently tell you - configuring IDE/ATAPI devices to
Cable Select (CS) is virtually always desirable. In the shops I've worked
in (over at least the past five years or so), *every* PC was configured
CS with respect to those devices. It simplifies maintenance enormously
when working on these machines and there's no downside to a CS
configuration.

As one responder to your query pointed out, it is (usually) important to
use a 80-wire signal (data) cable rather than the 40-wire (connector)
cable when configuring CS. (It's a curse that nearly all the retail,
boxed versions of optical drives are still coming bundled with 40-wire
cables just to save the manufacturer a few pennies).

I must add, however, that every once in a while - even where a modern
motherboard is involved - we have run into a drive recognition problem
when using CS rather than a M/S jumper configuration. It's an extremely
rare situation (at least in my experience) but it has occurred. But when
it does happen it's immediately apparent and simple enough to change.
