If you mean the  Start = 2048 in the output, that's done automatically to
accommodate what are called "Advanced Format drives". AKA "4k sector
drives".

Starting the partition there is said to greatly increase performance for
those drives because it causes a correct alignment of the partition.

Current versions of Gparted will suggest you start the partition there.
Ubuntu does the same thing when installing the default drive layout.
(letting it use the entire disk)

Windows 7, and I think Vista does this too.

Can't help with the heads vs. sectors differences. That is something that
they can vary like that. Were they the same model? Made in the same country?
