Probably correct, we see this all the time.
So called "expert PC guy" opens the (encrypting) caddy, removes the HDD and runs a quick format in order to recover the data. So of course the newly written MBR etc is unencrypted whereas the rest of the data is still encrypted.
It maybe that the box (or rather the encrypting USB bridge) is faulty, but also possible that the drive has bad sectors preventing the bridge from initialising the Smartware properly. But as you say you've run a full scan, I'd say the drive is in good shape.
Try seeing if the drive is seen by your recovery software when it's connected via the usb bridge, or if it's dead then you'll need another identical one.
Good luck!
