Ok, I called him, he called me back, VERY busy guy, good intentions, is sending me another unit. He tested this one to make sure it at least spins up (it was strange that while the auction ad made no mention of whether the drive had or had not been tested, that they still offered a 2-day DOA warranty). For my part, I'd decided that if a second unit is bad, hey, it was only $15.00, so no real harm done. But getting a working one means a lot, so I'm hoping this one will be good. At any rate, I feel safe saying that this guy runs a good business, and I'll probably buy whether the second unit works or not. -doug q
