GParted LiveCD と Parted Magic

The power and simplicity of GParted on a biz-card size LiveCD.

The CD aims to be fast, small in size (~50mb), and use minimal resources to get that disk partitioned the way you want it.
GParted LiveCD is based on Gentoo-catalyst, and uses Xorg,the lightweight Fluxbox window manager, and the latest 2.6 Linux Kernel.

Parted Magic is a Linux LiveCD/USB/PXE with its elemental purpose being to partition hard drives.

Optimized at approximately 30MB, the Parted Magic OS employs core programs of GParted and Parted to handle partitioning tasks with ease, while featuring other useful programs (e.g. Partition Image, TestDisk, fdisk, sfdisk, dd, ddrescue, etc.) and an excellent set of documentation to benefit the user.
An extensive collection of fileystem tools are also included, as Parted Magic supports the following: ext2, ext3, ext4, fat16, fat32, hfs, hfs+, jfs, linux-swap, ntfs, reiserfs, reiser4, and xfs.

この2つは、Windows Vista未満だとできないパーティションのサイズ変更ができるCD1枚で動くLinux。
加えて Parted Magic は他にも様々なツールが入っているみたい。

GParted LiveCD を試してみたけど、漢字のフォントが入っていないみたいでその部分は文字化けする。
英語でも使えるのでそっちに設定して起動するのがおすすめ。
