Where can I find out about Partition Magic?

PartitionMagic is capable of resizing NTFS or FAT (16 or 32) partitions without data loss, and can copy and move partitions, including to other disks. It also has various other features, including being able to convert between FAT16, FAT32 and NTFS, modify the cluster size of FAT16/32 and NTFS filesystems, and merge adjacent FAT or NTFS filesystems (all without data loss, though some NTFS-only metadata is lost on conversion to FAT). Additionally, it has somewhat limited support for ext2 and ext3 partitions.
