Trying to recover data from an external HDD

Hello everyone and anyone,

I was a bit careless and my main external HDD took a small drop. Since the drop it won't boot up anymore:
- If I boot my Win7 PC with the HDD connected it will often fail to boot.
- If connected the drive will try to spin up and give up after a few tries.
- the drive shows in device manager, but fails to show in disk management (so it's not a drive-letter issue)

Before I go and open it up to check if the head's busted, I thought I'd see if I've exhausted every option.
What I've tried so far:
- Recovery software in win7 and through a linux bootable USB (Partitionedmagic) using every possible connection except for putting it straight into the PC itself.
- Switched external casings (with a confirmed working one) and tried everything again.

I checked the PCB, but I can't see anything wrong with it.

Back in it's original (now confirmed working as well) I ran UVC and HDsentinel.
HDsentinel doesn't pick it up.
UVCview gives me:

What irks me a bit is the max Power of 0 mA. But I'm not a pro, so that could just be nothing.

Anyone have any ideas short of a board replacement, the ol' tap or opening it up to check head and platters?

Edit: Forgot to add: it's a WD15EARS 1.5 TB, MDL: WD15EARS-00MVWB0

Thanks ahead.
