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).

These features can be used for example for file recovery. 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. Some disk editors include special functions which enable more comfortable ways to edit and fix file systems or other disk specific data structures. However, modifying such data structures gives only a weak level of protection and data encryption is the preferred method to achieve privacy. 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. Programmers can use disk editors to understand these structures and test whether their implementation (e.g. 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. Many disk editors can also be used to edit the contents of a running computer's memory or a disk image. 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).
