xp won't use it correctly either.  in fact, if you're using a standard
fdisk layout, chances are things are a little sideways on nearly any
os.

in any event, if i were buying a 2t hard drive today, i'd get
	http://www.newegg.com/Product/Product.aspx?Item=N82E16822136365
since i'm paranoid about hard drives and only get enterprise ones.
if you're not, then (most) anything with 512-byte sectors should be no
troubles.  the easiest way to check is to do some math.  multiply
the number of sectors (that's always on the datasheet) by the
512, and see if that equals the claimed capacity.
