- FORMAT
- Initializes a disk or partition to accept MS-DOS files
- See also <SYS> <LABEL> <VOL>
-
- FORMAT checks for any defective tracks, and prepares the disk to
- accept DOS files. It creates the directory and file allocation tables
- (FAT) and assigns a unique volume serial number. It may also
- optionally copy the MSDOS system files to the new disc.
-
- COMMAND TYPE: External VERSION: 2.0 and up
-
- USE: FORMAT d:[/S][/1][/4][/8][/B] [/n:sectors][/t:tracks][/v:label]
- [/f:size]
-
- d: is the drive to be formatted.
- /S copies the system files from the source disk to the destination
- disk and makes the disk bootable. There are three system files:
- IBMBIO.COM IBMDOS.COM COMMAND.COM
- (these files may have different names on non-IBM systems)
- /1 formats a diskette on 1 side only making it a single sided
- diskette regardless of the drive type used.
- /4 formats a 360k (DSDD) diskette in a high capacity drive. Such disks
- may not always be read reliably by 360k drives because of the narrower
- tracks.
- /8 formats a disk using 8 sectors per track. (Obsolete - required to
- remain compatible with version 1.1 of DOS)
- /V will allow you to add a volume label to the diskette being
- formatted. Volume labels are a way to identify individual
- diskettes. The label (up to 11 characters) may be specified after /v
- or will be prompted for when formatting is complete.
- /B formats a diskette using 8 sectors per track and allocates space
- for system files to be transferred later (using the SYS
- command). Using the /B option will allow you to install any
- version of the DOS system files.
-
- (MSDOS 4.x extensions)
- /t:tracks specifies the number of tracks to place on the disc
- /n:sectors specifies the number of sectors to place on the disc
- /f:size specifies the size of the diskette. MSDOS chooses the
- appropriate number of tracks and sectors. Allowable values are
- 160k 180k 320k 360k 720k 1200k 1440k (may be specified with
- "k", "kb" or neither). This cannot be used the /t or /n
-
- By default, FORMAT will use the drive specification to determine the type
- of disc according to the the physical drive addressed by that letter. If
- it is a non-removable hard disc, FORMAT will request confirmation before
- proceeding.
-
- EXAMPLE: FORMAT C: /S /V
- FORMATS drive C:, copies the SYSTEM files to drive C:, and prompts the
- user for a VOLUME LABEL.
-
- NOTE: FORMAT destroys any existing data on the disk, and ignores any
- drive reassignments made via the <ASSIGN> command.
