Hey there, was just wondering if there is a way to shrink/split my 1TB hdd.. I've done it in the past from the Windows instalation process, but it didn't let me this time, so I just figured I'd go ahead and install Windows.. I used to have the same drive, it allowed me to shrink/extend/create a new partition, but this time it didnt work, now my guestion goes: How can I split this 1TB HDD So I'd get 200gb on my C (Main partition) and 731 on my D: just like my old HDD?

It only allowes me to shrink it in half instead of creating a new partition..
