A software package by PowerQuest that allows you to repartition your hard drive nondestructively. Before PartitionMagic, the only way to acomplish this was to use a DOS program called FIPS, which is less advanced. PartitionMagic supports the FAT, FAT32, NTFS, HPFS, and ext2 file systems.

One day, PartitionMagic was bad and trashed my 10gb FAT32 partition.
