A disk editor is a computer program that lets the user read, edit, and write the low-level raw data on a disk drive (a hard disk or floppy disk drive). Such an editor may be used e.g. to repair/reconstruct damaged files and directories (and, for that matter, damage them in the first place).
Disk editors for home computers of the 1980s were often included as part of utility software packages on floppies or cartridges. The latter had the advantage of being instantly available at power-on and after resets, instead of having to be (re)loaded on the same disk drive that later would hold the floppy to be edited (the majority of home computer users possessed only one floppy disk drive). Having the disk editor on cartridge also helped the user avoid editing/damaging the disk editor application disk by mistake.
