It's generally not a good idea to hook a/c powered devices together
without first determining if they are on the same phase. An easy way

I guess we've probably bored the OP such that he's given up reading the
thread so won't tell us. But when he said "Periodically, I want to
remove a drive, take it over to my 24-7 PC, and run tests on the
drive.", it sounded to me like he _wasn't_ wanting to connect together
the two machines, just find a way of removing without having to do the
screws every time.

Your - and Paul's - warnings about connecting together machines are of
course valid. (And interesting to a UK reader: within _domestic_
premises here, we're nearly always on only one [220-240V] phase, though
the neighbour is probably on the next phase, so unwise to interconnect
across the garden fence!)
