A disk editor is a computer program that allows its user to read, edit, and write raw data (at character or hexadecimal, byte-levels) on disk drives (e.g., hard disks, USB flash disks or removable media such as a floppy disks); as such, they are sometimes called sector editors, since the read/write routines built into the electronics of most disk drives require to read/write data in chunks of sectors (usually 512 bytes). Many disk editors can also be used to edit the contents of a running computer’s memory or a disk image.
Unlike hex editors, which are used to edit files, a disk editor allows access to the underlying disk structures, such as the MBR, volume boot records, file system, and directories. Programmers can use disk editors to understand these structures and test whether their implementation (e.g. of a file system) works correctly. Sometimes these structures are edited in order to provide examples for teaching data recovery and forensics, or in an attempt to hide data to achieve privacy or hide data from casual examiners. However it should be noted that modifying such data structures gives only a weak level of protection and data encryption is the preferred method to achieve privacy.
Some disk editors include special functions which enable more comfortable ways to edit and fix file systems or other disk specific data structures. Furthermore some include simple file browsers that can present the disk contents for partially corrupted file systems or file systems unknown to the operating system. These features can be used for example for file recovery.
History
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 at that time). Having the disk editor on cartridge also helped the user avoid editing/damaging the disk editor application disk by mistake.
