Editing Disk partitioning (section)

==History==

One of the earliest such forms of segmentation of a disk drive was IBM's 1966<ref name="IBMJRD" /> usage in its [[CP-67]] operating system of ''minidisk'' as a separate segment of a hard disk drive.<ref name="ref2" />

[[Data General]]'s [[Data General RDOS|RDOS]] operating system for their [[Data General Nova|Nova]] computers used the term ''partition'' for subregions of a disk. Each partition had its own directory.<ref>{{cite book |url=http://www.bitsavers.org/pdf/dg/software/rdos/093-000083-02_RDOS_Intro_1972.pdf |title=Introduction to the Real Time Disk Operating System |page=11 |publisher=[[Data General]] |date=1972}}</ref><ref>{{cite book |url=http://www.bitsavers.org/pdf/dg/software/rdos/093-000075-08_RDOS_Reference_Manual_Mar79.pdf |title=Real Time Disk Operating System (RDOS) Manual |pages=2{{hyp}}9-2{{hyp}}11 |publisher=[[Data General]] |date=March 1979}}</ref>

IBM in its 1983 release of [[Fdisk#IBM PC DOS|PC DOS version 2.0]] also used the term ''partition'' to describe dividing a block storage device such as an [[Hard disk drive|HDD]] into physical segments.  The term's usage is now ubiquitous.{{cn|date=August 2023}} Other terms used include ''logical disk'',<ref name="ref1" /> ''minidisk'',<ref name="ref2" /> ''portions'',<ref name="ref3" /> ''pseudo-disk'',<ref name="ref3" /> ''section'',<ref name="ref3" />  ''slice''<ref name="ref4" /> and ''virtual drive''.<ref name="ref5" />
