I want to partition my laptop HD. Its a 250Gb HD. I download random things all the time usually by bittorrent software since its much faster than most companies FTP servers. I want to have 25Gbs of storage on a seperate partition. When I go into the Disc Management console in Vista it says I can only shrink the main partition by 180Mbs when I have 172Gbs available. Any clue on what I can do?
