Disc format

1,109 bytes added, 18:58, 28 September 2006
CPCs could read discs formatted in three separate ways. Several high-capacity disc operating systems existed to add new formats to the three standard ones.

== Standard CPC disc formats ==

* '''Data''': 180k single-sided. 40 tracks of nine 512-byte sectors each. Sectors numbered &C1 to &C9. 64 directory entries. Can also be read by [[PCW]]s.
* '''System''': 180k single-sided. 40 tracks of nine 512-byte sectors each. Sectors numbered &41 to &49. 64 directory entries. Two reserved tracks containing CP/M BIOS.
* '''IBM''': 40 tracks of eight 512-byte sectors each. Sectors numbered &01 to &08. Provided for compatibility with CP/M-86 (?).
* '''Vendor''': Term used for System format discs with no software in the reserved tracks.

== Third-party CPC disc formats ==

* [[Xexor]] formats (also supported by [[ParaDOS]])
* [[ROMDOS]] formats (also supported by [[ParaDOS]]: D80 supported by [[S-DOS]] and [[400K/S]])
* [[MS800]] formats
* [[RODOS]] formats
* [[Ultraform]]
* XD-DOS etc.??
