Believe one of my bootable rescue isosFinal thing to do maybe is to take the drive out of the usb enclosure, connect it direct to motherboard and run Victoria on it. Victoria being a hard drive fixing/recovery tool which seems to have some notoriety.
Has Victoria on it
Not sure ever actually used it though
But he's already said
"From what I can gather, the board on this drive has a built-in USB interface, it's not an adapter so can't connect it to SATA"
A lot of drives now can't be shucked out the enclosure
And used as internal drives
