As it does on a mate's PC who I'm trying to copy these files for (it's his port.
HDD that I'm using).

Dunno how. You plug one end into the port, the other into the HDD...

Not using any hubs. The ports at the front work fine for other peripherals and
only one HDD connected. The ones on the back are on the motherboard's backplane
or whatever it's called. Tried a different combo with no success.

Same thing. Only the first connected drive is recognised....

It isn't, or so Device Manager tells me. And it only has the one cable.

I did have one of those, though. And it did the same thing, even with the two
cables connected.

So it cant be XP SP2.

No, I meant the cable inside the PC case, between
the motherboard and the front physical port.

Yes, but you can get the effect you are seeing with some bad internal cables.

Did you try with both drives on USB ports on the back that are soldered into the motherboard ?

That eliminates any cable.
