Hello,
I am looking at purchasing the Maxtor M01E100 External Hard Drive and am wondering if it has to be powered by the included AC power adapter? Can it be powered solely by USB? Or will I always have to be around an outlet when I want to use it?

Also, if you guys have any suggestions on other good external hard drives, feel free to post them. Thanks!

USB ports can only supply a Max of 500 mA.
As it's a 3.5" drive, its certainly going to be around 1 to 1.5 amps required.

Even using a dual USB jumper to power it from two ports is likely to fail.

2.5" notebook HDD's have lower consumption, they can sometimes be OK on dual port supply but it's often touch and go on them as well. I have a 30 GB 2.5" external that works on some (but not all) PCs using a dual head lead, its marginal.

The Maxtor may not even be configured to use the USB power if its designed for a mains adaptor.

My 2.5" drives, a 60gig and a 30gig both work with a dual USB cable, but there's no hope for any 3.5" drive doing so. First off, you need about an amp of +12V for those, and that would translate into about 3A of +5V from the USB supply. The 2.5W of power supplied by the USB port just isn't going to stretch into 15-20 watts that the typical 3.5" drive requires.
