External USB Enclosure Fried My Drives

RE: 2 Maxtor D540-X-4K
I had all my data backed up on 2 hard drives.
I was switching from a desktop to notebook/desktop replacement.
I attached the drives to an external USB enclosure.
Both were not recognized as USB (on anything) by WIN XP.
I then tried the drives in a working computer and both cannot be seen
by the BIOS.
I tried them as slaves and masters, no go.
I am pretty sure the USB enclosure/cable or its power supply fried the
drives IDE.
I think that replacing the drive electronics board will get my drives
working so that I can retrieve my data.
I've never done this before, I replaced power supplies, memory,
complete drives etc.
Any schematics on how this is accomplished.
Any help would be appreciated

Possible. But also inserting the IDE cable upside-down will generate the
same results of not having a detectable hard drive. Haste makes waste.
Might want to double-check that the Pin 1 side of the cable coincides
throughout.
