With diskpart, scripts are supported to facilitate such functions. For example, the code below would create a new partition: create partition logical size=2048 assign letter=F Specifically, the above will create a 2 GB logical partition, provided that adequate space is available, and assign it the drive letter 'F:'. [5]
With this option, Format writes bootstrap code to the first sector of the volume (and possibly elsewhere as well). Format always writes a BIOS Parameter Block to the first sector, with or without the /S option. Another option (/Q) allows for what Microsoft calls "Quick Format". With this option the command will not perform steps 2 and 3 above.
convert is an external command first introduced with Windows 2000. [2] If the drive cannot be locked (for example, the drive is the system volume or the current drive) the command gives the option to convert the drive the next time the computer is restarted.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
"M" represents the drive letter to assign a custom label to. However, labels created for SUBST drives in this manner are overridden by the label of the host drive/partition: the custom labels are only used if the host drive has no label. One may then: Delete the host's drive label; Create the proper registry keys for the SUBST drive letter;

Formerly, on disks formatted using the master boot record (MBR) partition layout, certain software components used hidden sectors of the disk for data storage purposes. For example, the Logical Disk Manager (LDM), on dynamic disks, stores metadata in a 1 MB area at the end of the disk which is not allocated to any partition.
fdisk is a command-line utility for disk partitioning.It has been part of DOS, DR FlexOS, IBM OS/2, and early versions of Microsoft Windows, as well as certain ports of FreeBSD, [2] NetBSD, [3] OpenBSD, [4] DragonFly BSD [5] and macOS [6] for compatibility reasons.
