GParted

GParted is an official disk partition editor for GNOME desktop, distributed under GNU GPL license. It allows one to create, delete, grow, shrink, copy and paste, clone, repair, and format disk partitions via an easy-to-use graphical interface. The support for these operations varies depending on filesystems used. GParted can handle disk partitions formatted in various file systems, including Btrfs, ext2/3/4, FAT16/32, HFS, NTFS, ReiserFS and XFS. GParted works with not only traditional disk drives, but also flash memory cards, USB memory sticks, SSDs, and hardware/software RAID. GParted is available as a standalone GUI tool, as well as a live CD/USB bootable image. The live GParted image is based on Debian Linux.
