My own Seagate USB external drives (while not this model) both have AC power
supplies with the input socket on the drive enclosure marked "12V DC 2.0A"
which seems to me to be a bit in excess of 5W, even at 12V. Of course, the
power supply is likely to be rated in excess of the drive's requirement, but
even so (as others have already commented) the ad is likely to be in error
in suggesting the drive is bus-powered.
And as mentioned in the past, my drives are connected as NAS, using the
impressive - and highly recommended - NSLU2.

Subject: [OM] [OT] External hard drive question
Anyone have experience with external hard drives powered by USB? My
recollection is that USB only provides 5 watts total to the bus. This 320
GB drive has to be 3-1/2" and, I would assume, must be drawing a pretty fair
share of the power available. What happens if other devices on the bus want
some of that power too? Is this a potentially unreliable drive solution?
