Two possible paths:
1. Try connecting the drive directly to the host computer as a slave. You
will need a laptop-to-IDE adapter.
2. Try a different USB enclosure.

This is an example of a 2.5" to regular ribbon cable adapter.
This is the side that connects to the regular ribbon cable.
Connect the drive to the ribbon cable end connector, by itself, on the assumption
the drive is master. The power connector provides +5V for the 2.5" drive.

This side is the part that plugs into the 2.5" drive. It has 44 pins,
40 for data and 4 on the end for power.

Some complaints, though, about it being flimsy. It is also possible
to put the power cable on backwards.

This one has a keyed power connector, so less chance of screwing up,
compared to the previous style.

The reason connecting directly to a ribbon cable is an advantage,
is you can check in the BIOS to see if the ID string is visible
for the drive or not. If the drive refuses to ID itself (assuming
the master/slave jumpering isn't the problem), then you'd guess the
drive controller is not able to complete initialization. Drives
need to read some data from "sector -1", before they can offer
service to the user.

With regard to your USB enclosure, you might also want to check
the master/slave options. If you need help with the drive,
please post the exact brand and part number on the drive label.
(To make it easy to look up jumper settings and specs etc.)
The USB enclosure I have in front of me here, has "master" written
in black letters on the cabling, leaving no doubt as to what
the enclosure wants to see for operating modes.
