FDISK COMMAND
Purpose: FDISK is used for:
- creating DOS partitions (logical disks);
- changing the active partition;
- deleting DOS partitions (logical drives) as well as
partitions of other operating systems;
- displaying fixed disk partition and logical disks information;
- selecting the next fixed disk (if the PC is equipped with
several fixed disks).
Syntax: FDISK [parameters]
Parameters:
/?, /H[ELP] - help,
/B[LACK] - display unused partitions,
/C[OMPATIBLE] - create MS-DOS compatible logical drives only,
/I[GNORE] - skip error messages on start,
/M[BR] - update MBR (master boot record) and quit,
/S[ECTOR] - create logical drives aligned by sector
Running FDISK involves consecutive execution of the following
operations:
1. Inserting a DOS diskette into the drive A: and restarting the system.

The following information about each partition is displayed:
"Partition" the number of partition; the word "Primary", if information
about the partition is in MBR;
"Drv" a drive letter, which MS-DOS would assign to the logical
drive;
"Status" the word "Adwanc", if the partition is advanced active,
the word "Active", if the partition is standard active.
"Type" partition type ("DOS-12", DOS-16", "BigDOS" are logical DOS
drives, "Extend" is an extended DOS partition containing
other partitions etc.);
"MBytes" partition size in MBytes;
"Notes" error messages if there are any.
