Faulty USB caddy on OSX

Preamble

I bought a USB caddy with a 500GB SATA 2.5″ HDD inside. Philips SDF3271SC/97 which may or may not be an original or a clone. It has a Mini USB connector, rather than a MicroUSB, which is an indicator of its age. It won’t mount on OSX 10.8.5

The error in the Console is as follows:

It is unclear whether the issue is with the USB controller or the disk. Fitting a new disk, to se if this resolves things, would help narrow down the issue.
