I had a similar experience with a Seagate 1 gig HD in an external box.
This one was a 5.25" full height drive- a major motor current hog.. 🙂 The
external box was a modified clone minitower case. I found that the typical
PC power supply isn't well (or at all) regulated on the 12v. If there's
not enough load on the 5 volts, there's not enough current capacity on the
12 volts. The drive appeared to spin up, but never actually went ready. I
finally had to hook up a dummy load – a 4 ohm 50 watt resistor – to the 5
volts. (But not before I had mistakenly sent the first drive back 🙁 )
