Gave up on the file copy - after about 12 hours, 2 of the 8 million files had
been 'prepared'. And even if it got as far as preparing, copy's by no means
guaranteed from the suspect disk.

Do you mean create an image, and copying that, using DU?

As it is I'm using a trial of Superduper - that's gone straight to copy, about
20GB/hr using USB3. So even that is going to take over a day to copy 500GB.
