I am looking for open source applications that will allow resizing hard drive partitions. I have used partition magic in the past but am looking for open source free applications that can handle this task.
I've used GParted Live CD in the past with success, it's a linux boot disk designed for partitoning. I should have mentioned that despite being a linux disk, it works for sorting out windows partitions too. I split my laptop up to install the windows 7 beta using this.
