Thanks for the feedback, Godders. The disk (a Western Digital 'My Book') has already been backed up to another - I went out and bought a 1.5 terabyte backup drive a few weeks ago when my other external drive (a Western Digital 'Essentials') died suddenly (that one was actually younger than the 'My Book' but my son installed it in a new enclosure and it seems to be OK so it was probably a faulty controller in that case). I originally bought the 'My Book' for my old PC which didn't have a large internal hard disk, so I was using the My Book drive as a second drive. I've since upgraded to a new PC with a large internal drive so I don't really need the external one any more. But, as you say, it could be useful as a temp or work drive so I'll double check the cable and then try it in a new enclosure.
