The focus of this category is on disk editors. Also known as sector editors, disk editors are software programs designed to read, edit, and write raw data on disk drives, at the character, hexadecimal, and byte-levels.

Many disk editors can also be used to edit the content of a running computer's memory or disk image.

Several hex editors also have disk editor features. While hex editors are used to edit files, disk editors access the underlying disk structures, such as the master boot record, volume boot records, file systems, and directories. Disk editors help programmers understand these structures, and to test whether their implementation works correctly. They may also be used to edit these structures as examples in teaching data recovery and disk drive forensics, or to hide data for various reasons.

Disk drivers sometimes include functions to facilitate the editing and fixing of file systems or other disk-specific data structures. File browsers might also be included, allowing the disk contents to be examined for corrupt file systems or file systems that are not recognized by the operating system. These features can aid in file recovery efforts.

An early disk editor was DEBUG, which was included in all versions of DOS. With DEBUG, users can load, edit, and write one or more sectors from a hard disk or floppy based on the BIOS, allowing simple disk-editing functions like saving and restoring the master boot record and other critical sectors, or changing the active partition in the master boot record.

A partition editor is a partitioning utility designed to view, create, modify, or delete disk partitions, which are logical segments of the storage space on a storage device. By partitioning a hard drive into several partitions, various types of data can be isolated from one another, allowing two or more operating systems to exist on the same hard drive.

Both disk editors and partition editors are appropriate topics for this category.
