hard disk not recognized

i'm running Windows XP SP1a, have a USB2.0 HDD enclosure hooked up
into a USB1.1 port, and am having problems reading certain hard
drives. specifically, when i insert OEM hard drives, from IBM laptops
(i've tried two), the hard drive is simply not recognized. It doesn't
show up in Disk Manager, so... even if i wanted to do what seems to
be the common suggestion (ie. reformat), i couldn't, because Windows
doesn't even see a hard drive for me to format. of course, that said,
i *don't* want to reformat, anyways. i want to backup data.

also, i *know* my USB2.0 HDD enclosure works, with the given setup,
because it works with non-OEM hard drives (although i haven't tried
any non-OEM hard drives that weren't formated, before i inserted them
in there).

so, anyways, any suggestions? i mean, surely there has to be a way to
backup data off of an OEM hard drive without booting off of that hard
drive?

Without looking I'd say that the most likely problem is that the jumper
setting is incorrect on the drive. I know that many OEM's have started
using cable select vs. master/slave-I'm not sure how this would affect a
drive connected via USB.

that wound up being the problem. i'm now using cable select.
however, the jumper that i'm using is kinda big and in fact the only
way that i can use it is to have the hard drive not fully connected to
the pins... ah well.

anyways, thanks for the tip!
