Uh. Did you disassemble this hard drive first? (I hope not.)
I start by re-inserting the drive back into the computer and see how it reacts, as if that SATA-IDE-USB box was 'bad'.
This hard-drive is a SATA, yes? Sometimes the plastic L-shaped connectors get broken - check those. If those are broken, then there's a major problem that we've sometimes solved by using the 'all in one' SATA connectors, like
where one 'connector' is actually helping the other connector stay in-place. But this has a limited value, by the way - broken plastic guides and connectors mean "drive is ready to die - save it while you can".
Next, let's assume the drive is dead. There's probably no way we can chat up the tests and results for that determination - I'd find a local specialist. Even if it's a custom PC shop, some guy in the backroom can help determine that, and he probably knows Recovery Services, too.
