The segfault seems to be related to unclutter, a mouse pointer hiding

Dead disk. Just today it stopped spinning the platters. The platters
were spinning when this test was made, but maybe not fast enough or
the drive has other problems. In any case, mystery solved.

I attach the power and IDE cables to the drive, then power it on, then
connect the USB to the computer.

Actually, I like to use a 5 kilo hammer when inserting drives. It
gives just enough inertia to dent the metal parts of the case without
cracking the plastic parts. And as the IDE ribbon is so slippery, I
like to hold it with something other than my bare hands when pushing
it into place. Scissors usually grip them well.
