Several weeks ago I posted a request for assistance with a hard disk
that was going "clunk, clunk, clunk" intermittently, and intermittently
failing to respond to the PC until I cycled the power. Thanks to
everyone who responded with advice and suggestions. The problem turned
out to be simpler than anyone guessed.
I opened up the external cabinet containing the disk drive and power
supply so that I could attach some probes to the power supply. When
I turned on the power, I noticed the power cable from the power supply
to the disk drive was occasionally contacting the fan blades ("clunk,
clunk, clunk" until the blades pushed the cable away). I disconnected
the power cable from the disk drive, then put them back together again
to test for deficiencies in the power supply. The disk drive has worked
without flaw now for over two weeks. Apparently, the fan blades were
jostling the power cable a little loose, causing the occasional
need to cycle power.
