OK, well I've just checked the labels on the drives and they're both rated
at 5V, 500mA. Reckon a ribbon like that can take 1A? (Of course,
presumably it would say in the documentation from wherever I managed to
find that sold these things, and failing that it could always be tested.

Hmm. I shall have to look around. Most (all?) of the stuff in the
Farnell catalogue seems to be 0.05" at a glance :/
