GNU Parted

GNU Parted is a comprehensive program that provides a range of tools for managing partitions and file systems. With this software, users can create, resize, destroy, check, and copy partitions, thereby facilitating the creation of space for new operating systems, reorganizing disk usage, copying data between hard disks, and disk imaging.

One of the standout features of GNU Parted is its support for a variety of disk labels, including raw access, MS-DOS partition tables, Intel GPT partition tables, MIPS partition tables, PC98 partition tables, Sun and BSD disk labels, and Macintosh partition maps.

However, there are several important things to note when using GNU Parted. For example, if you're working with ext2, ext3, or reiserfs, the start of the partition must stay fixed. Additionally, when copying from ext2, ext3, the partition you copy to must be bigger or exactly the same size as the partition you copy from. When it comes to checking ext2 and ext3 partitions, the software only ensures that the resize and copy commands will be okay.

Another important consideration is that the size of the new partition after resizing or copying is restricted by the cluster size when using FAT. While Parted can shrink the cluster size to allow you to shrink your partition, growing it may not be possible if you can't use FAT32. However, with support for both FAT16 and FAT32, Parted can still help you navigate these limitations.

Overall, if you're looking for powerful partition and file system management tools, GNU Parted is definitely worth checking out. It even includes support for reiserfs if you choose to install libreiserfs.
