Partitioning problem please help

[shaun88]

i've just built my first pc and want to partition my new hard drive 1TB
i would like my C drive (obv including the OS) to be around 150GB and my patitioned D drive around 750GB
this is my first step: http://puu.sh/1Tots
but i cant make a D drive around 750GB, the most it will let me do is 468GB as seen here where it says "size of available shrink in MB: 468385" http://puu.sh/1TotP
is there a way around so i can shrink more?

So why did you create a c partition of 900Gb in the first place? You should have create c with 150Gb at system install. Now you have to shrink the existing partition and that is limited by files spread over c. Try to run defrag. it might relocate some files, so you can shrink a bit more.

it's the first time i've ever partitioned, i didnt realise i'd be limited via windows way but never mind
