GParted – Free Partition Editor


GParted is a free and open source partitioning tool. It can run within a Linux environment or can be booted from a live CD. GParted supports multiple file systems and works great on servers in RAID configurations.

GParted is very useful when a technician needs to re-size a partition, re-format a drive (to a different file system), set the boot flag to a partition, and perform other useful features. Recently this program was used in a small business environment on two different servers in RAID 5 configurations. Both servers were running Windows Server 2003 and had a system partition (C: drive) size of only 12 GB.

Obviously this is too small for a system partition by current standards, and it was at the point where these servers could not download and install updates. One server had about 400GB of information stored on it with a couple hundred free. We were able to successfully boot into GParted and re-partition the drives on both of these servers without any problems (boosted the C: drive partition to around 40GB).

I have used GParted many times on workstations and I can’t remember a time when it has failed or I lost data. It’s a great tool that all technicians should have in their toolkit. It can be downloaded as an ISO and burned to a bootable standalone cd, and many times comes included on multi-application boot/rescue cd’s.

    Another good tool, and my favorite, is Easeus Partition Master.

    This is a good free alternative though, thanks.

    The Parted Magic OS employs core programs of GParted and Parted to handle partitioning tasks with ease

    I have used Gparted for years and really never needed to try another program of this type.

    I did run into a problem once that bugged me for over a day. It is not clear if it was a problem with Gparted or the motherboard/BIOS. If you have problem with a disk drive being identified correctly such as having the correct letter assinment, disconnect any card reader connected to the motherboard. Some motherboards do not properly identify the disk drives when booted to a variant of Unix.

    I’m planning to use gparted to re-size some partitions on a work computer, but it a windows server rather that windows standard, should this make any difference?
