It is a 2.5 inch HDD - model "Toshiba Canvio V63700-C 1TB 2.5" USB 3.0 Hard Disk Drive". There is certainly NO detection when plugged in front (USB3) port - but, as I've said previously, it is immediately recognised when plugged in a back (USB2) port. Unfortunately, its the only USB3 drive (of any type - 'rotating' or memory stick) that I have, so I can't check with another model. It certainly does look like it is a specific brand/model problem.
We know the port is - fundamentally - OK, and we know the drive is OK - as long as it is in another port! It's interesting, as I do have a desktop (Windows) machine with a USB3 port, and the drive is recognised as such when plugged in there (and it is definitely faster). Recall, though, I did have a problem with a Verbatim USB 'stick' so brand / model / "specification" issues may not be that uncommon!!
