Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk, memory card or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems. The first part of the formatting process that performs basic medium preparation is ...
The diskpart utility is used for partitioning internal hard drives but can also format removable media such as flash drives. [ 4 ] It has long been possible, theoretically, to partition removable drives – such as flash drives or memory cards – from within Windows NT 4.0 / 2000 / XP; e.g., during system installation.
If the actual size of the disk exceeds the maximum partition size representable using the legacy 32-bit LBA entries in the MBR partition table, the recorded size of this partition is clipped at the maximum, thereby ignoring the rest of the disk. This amounts to a maximum reported size of 2 TiB, assuming a disk with 512 bytes per sector (see 512e).
Disk partitioning or disk slicing [1] is the creation of one or more regions on secondary storage, so that each region can be managed separately. [2] These regions are called partitions. It is typically the first step of preparing a newly installed disk after a partitioning scheme is chosen for the new disk before any file system is created.
In computing, format is a command-line utility that carries out disk formatting. It is a component of various operating systems , including 86-DOS , MS-DOS , IBM PC DOS and OS/2 , Microsoft Windows and ReactOS .
In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. For most disks, each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs), and 2048 bytes for CD-ROMs , DVD-ROMs and BD-ROMs . [ 1 ]

The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
