Design rule for Camera File system (DCF) is a JEITA specification (number CP-3461) which defines a file system for digital cameras, including the directory structure, file naming method, character set, file format, and metadata format.
Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) [5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.

Drives with this capability are known as self-encrypting drives ; they are present on most modern enterprise-level laptops and are increasingly used in the enterprise to protect the data. Changing the encryption key renders inaccessible all data stored on a SED, which is an easy and very fast method for achieving a 100% data erasure.
A flash file system is a file system designed for storing files on flash memory–based storage devices. While flash file systems are closely related to file systems in general, they are optimized for the nature and characteristics of flash memory (such as to avoid write amplification ), and for use in particular operating systems .
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 ...
When child welfare workers and police knocked on Sarah Perkins’ and Joshua Sabey’s front door well past midnight one weekend last summer, the parents were shocked to learn the state of ...
The preferred file system is the Universal Disk Format (UDF) in versions from 1.50 onward, which is also used by DLA. Packet writing is not required for writing DVD-RAM . DVD-RAM media are already sectored (which can be seen when looking at the surface of an empty DVD-RAM disc) and the hardware logic of DVD-RAM capable drives supports sectored ...
