  2. fdisk - Wikipedia

    en.wikipedia.org/wiki/Fdisk

    IBM introduced the first version of fdisk (officially dubbed "Fixed Disk Setup Program") in March 1983, with the release of the IBM PC/XT computer (the first PC to store data on a hard disk) and the IBM PC DOS 2.0 operating system. fdisk version 1.0 can create one FAT12 partition, delete it, change the active partition, or display partition data. fdisk writes the master boot record, which ...

  3. Partition type - Wikipedia

    en.wikipedia.org/wiki/Partition_type

    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 ...

  4. Microsoft Reserved Partition - Wikipedia

    en.wikipedia.org/wiki/Microsoft_Reserved_Partition

    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.

  5. Microsoft basic data partition - Wikipedia

    en.wikipedia.org/wiki/Microsoft_basic_data_partition

    According to Microsoft, the basic data partition is the equivalent to master boot record (MBR) partition types 0x06 , 0x07 (NTFS or exFAT), and 0x0B . [2] In practice, it is equivalent to 0x01 ( FAT12 ), 0x04 ( FAT16 ), 0x0C (FAT32 with logical block addressing ), and 0x0E (FAT16 with logical block addressing) types as well.

  6. Disk partitioning - Wikipedia

    en.wikipedia.org/wiki/Disk_partitioning

    The total data storage space of a PC HDD on which MBR partitioning is implemented can contain at most four primary partitions, or alternatively three primary partitions and an extended partition. The Partition Table, located in the master boot record, contains 16-byte entries, each of which describes a partition.

  7. Boot sector - Wikipedia

    en.wikipedia.org/wiki/Boot_sector

    A master boot record (MBR) is the first sector of a data storage device that has been partitioned. The MBR sector may contain code to locate the active partition and invoke its volume boot record. The MBR sector may contain code to locate the active partition and invoke its volume boot record.

  8. Disk formatting - Wikipedia

    en.wikipedia.org/wiki/Disk_formatting

    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 ...

  9. Master boot record - Wikipedia

    en.wikipedia.org/wiki/Master_boot_record

    Support for partitioned media, and thereby the master boot record (MBR), was introduced with IBM PC DOS 2.0 in March 1983 in order to support the 10 MB hard disk of the then-new IBM Personal Computer XT, still using the FAT12 file system. The original version of the MBR was written by David Litton of IBM in June 1982.
