In 2010, hard-disk manufacturers introduced drives with 4,096‑byte sectors (Advanced Format). [3] For compatibility with legacy hardware and software, those drives include an emulation technology ( 512e ) that presents 512‑byte sectors to the entity accessing the hard drive, despite their underlying 4,096‑byte physical sectors.

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.
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 ...
(Windows drive letters do not correspond to partitions in a one-to-one fashion, so there may be more or fewer drive letters than partitions.) Microsoft Windows 2000 , XP , Vista , and Windows 7 include a ' Disk Management ' program which allows for the creation, deletion and resizing of FAT and NTFS partitions.
Starting with Windows Server 2022 and Windows 11, the boot environment natively supports ReFS, allowing the system to be installed and run in a special way on a volume formatted with ReFS v3. If it is a volume formatted with ReFS v1, it cannot be booted with ReFS.
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 .

The Linux kernel has supported USB mass-storage devices since version 2.3.47 [3] (2001, backported to kernel 2.2.18 [4]).This support includes quirks and silicon/firmware bug workarounds as well as additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA-USB bridges, used for S.M.A.R.T. or temperature monitoring, controlling the ...
