Rough estimate of maximum HD power consumption?

I was talking to a few folks on another forum who swore up and down that a 7200 RPM hard drive pulls more amps to spin up than a "typical" CPU would under 100% load. Obviously this struck me as ridiculous. I was wondering if anyone had heard a rough figure for HD start up? I searched and searched, no luck though
Thanks for any help

samsung lists about 10 watts for their sp80,
given the size, volume, surface area, metal, and mass, 10 watts spread out over 3 dimensions results in little heat.
p4's can use 100+ watts in a 2-dimensional chip the size of your fingernail.

Lots of power draw figures from Takaman's PSU calculator:

Hard drive spin up for a WD 7200rpm 80GB is no more than 20 W. I was using a Kill A Watt device to measure this.
