Just don't be surprised later when you
add up the sizes of your partitions in
Windows it won't match what it says
on the box ( it will be smaller),
because manufacturers use 1MB = 1000KB
while everybody and everything including windows
uses 1MB = 1024KB. So basically you "lose"
24KB on every MB, and the bigger the HD the
bigger the "loss" from what it says on the box.
