Parted Magic is a LiveCD/USB with it's only purpose being partitioning hard
drives. Although GParted and Parted are the main programs, the CD/USB also
offers programs like partimage, testdisk, fdisk, sfdisk, dd, etc. By default,
Parted Magic boots (from CD, USB drive, or PXE) to a live version of Linux
(including a low-ram version) and provides access to the aforementioned
GParted partition creator and editor, a system profiler, several imaging
utilities, a benchmark utility, ISO image editor, a couple of file managers,
and a host of other utilities. (in System Utilities)
