I have used Gparted the recently in the past 2 yesars and on several serves to resize those pesky small dell Windoes O/S partitions and it worked great and would highly recommend- Used it on very big partitions - 750 G and up and worked like a champ - It just took some time due to the resizing of large amounts of data/space but very awesome and can be run from a iso cd/dvd or memory stick
