Parted Magic

Parted Magic is a commercial Linux distribution with disk partitioning and data recovery tools, sold as a Linux-based bootable disk. The distribution's nomenclature is derived from the names of the GNU Parted and PartitionMagic software packages.
Features.
The program is directly bootable from a CD, USB flash drive, or through a network using PXE on PC hardware, and does not require installation, or the presence of an installed operating system.
Although originally designed for mechanical hard disk drives, Parted Magic is suitable for use also with solid state drives and can perform an ATA Secure Erase (a method that is built into the hard drive controller to return the drive into its factory state).
Parted Magic supports reading and writing to a variety of modern file systems, including ext3, ext4, FAT, exFAT, and NTFS, and as such is able to access disk drives formatted for use under Microsoft Windows and Linux systems.
The software distribution includes networking support, and comes with the Firefox web browser.
System requirements.
As of version 11.11.11, Parted Magic supports Intel x86 and x86-64 processors natively, and requires a computer with at least an i586 Intel-compatible processor and 175MB of RAM. x86 versions from 2013_09_26 do not require the Physical Address Extension (PAE) computer processor feature.
Availability.
Up to version 2013.08.01 the distribution was freely available for download from the official website and the project page on SourceForge. The distribution moved to a pay-for-download business model, despite the packaged software being free and open source.
