  2. Volume Table of Contents - Wikipedia

    en.wikipedia.org/wiki/Volume_Table_of_Contents

    With the exception of the IBM Z compatible disk layout [1] [note 2] in Linux on Z, [2] it is the functional equivalent of the MS/PC DOS File Allocation Table (FAT), the NTFS Master File Table (MFT), and an inode table in a file system for a Unix-like system.

  3. Block (data storage) - Wikipedia

    en.wikipedia.org/wiki/Block_(data_storage)

    The process of putting data into blocks is called blocking, while deblocking is the process of extracting data from blocks. Blocked data is normally stored in a data buffer, and read or written a whole block at a time. Blocking reduces the overhead and speeds up the handling of the data stream. [3]

  4. Disk sector - Wikipedia

    en.wikipedia.org/wiki/Disk_sector

    This specifies the size of the chunks of data as delivered by dd, and is unrelated to sectors or filesystem blocks. In Linux, disk sector size can be determined with sudo fdisk -l | grep "Sector size" and block size can be determined with sudo blockdev --getbsz /dev/sda. [14]

  5. GUID Partition Table - Wikipedia

    en.wikipedia.org/wiki/GUID_Partition_Table

    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).

  6. Comparison of file systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_file_systems

    Note that in addition to the below table, block capabilities can be implemented below the file system layer in Linux (LVM, integritysetup, cryptsetup) or Windows (Volume Shadow Copy Service, SECURITY), etc.

  7. 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 ...

  8. Block allocation map - Wikipedia

    en.wikipedia.org/wiki/Block_allocation_map

    In computer file systems, a block allocation map is a data structure used to track disk blocks that are considered "in use". Blocks may also be referred to as allocation units or clusters. [1] CP/M used a block allocation map in its directory. Each directory entry could list 8 or 16 blocks (depending on disk format) that were allocated to a file.

  9. ext2 - Wikipedia

    en.wikipedia.org/wiki/Ext2

    The reason for some limits of ext2 are the file format of the data and the operating system's kernel. Mostly these factors will be determined once when the file system is built. They depend on the block size and the ratio of the number of blocks and inodes. [citation needed] In Linux the block size is limited by the architecture page size.
