Nope it doesn't matter. Drive selects are done with jumpers on the

That is just so much misleading, not to mention outright wrong,
information. Kindly stop leading people down the garden path.
On 40-wire cables, all pins will not be wired through if it's a
cable-select cable. On one plug a pin will be disconnected, on another
I've never seen a 40 pin CS cable.
plug a pin will be disconnected from the cable and grounded. These need
to be connected properly if using cable-select, but can be used any way
around if you're manually jumpering drives.
This is true in theory, and in my experience in practice, and superior
IMO to using CS.
On 80-wire cables, the same applies (as above) for cable-select
features, AND there's 40 other wires between the data lines that are
only grounded at the motherboard end. These NEED to have the
motherboard plug plugged into the motherboard, or you're risking a lot
of data corruption or interface problems, but the master and slave
connectors only need to be used as labelled if you're using the drives
in cable-select mode.
If one is hiding parts of cables out of the way, one should be careful
how it's done. Kinking or mangling cables can produce problems. If
you're *never* going to use the extra length, I'd suggest just cutting
it off.
Umm, won't work if using CS, because the middle connector is the
"slave". But I sure wouldn't leave a bunch of cable dangling after
a connector.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
