Gparted Live Cd

GParted is an industrial-strength package for creating, destroying, resizing, moving, checking and copying partitions, and the filesystems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data residing on hard disks and mirroring one partition with another (disk imaging). 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 uses Xorg, the lightweight Fluxbox window manager, and the latest 2.6 Linux Kernel.
