In software development, time-of-check to time-of-use ( TOCTOU, TOCTTOU or TOC/TOU) is a class of software bugs caused by a race condition involving the checking of the state of a part of a system (such as a security credential) and the use of the results of that check. TOCTOU race conditions are common in Unix between operations on the file ...

Write blocking, a subset of write protection, is a technique used in computer forensics in order to maintain the integrity of data storage devices. By preventing all write operations to the device, e.g. a hard drive, it can be ensured that the device remains unaltered by data recovery methods.
The Linux kernel has supported USB mass-storage devices since its 2.4 series (2001), and a backport to kernel 2.2.18 [2] has been made. In Linux, more features exist in addition to the generic drivers for USB mass-storage device class devices, including quirks, bug fixes and additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA ...
Write once read many. Write once read many ( WORM) describes a data storage device in which information, once written, cannot be modified. This write protection affords the assurance that the data cannot be tampered with once it is written to the device, excluding the possibility of data loss from human error, computer bugs, or malware .
File locking is a mechanism that restricts access to a computer file, or to a region of a file, by allowing only one user or process to modify or delete it at a specific time and to prevent reading of the file while it's being modified or deleted. Systems implement locking to prevent the classic interceding update scenario, which is a typical ...
The phenomenon of disk failure is not limited only to drives, but also applies to other types of magnetic media. In the late 1990s, Iomega's 100-megabyte Zip disks used in Zip drives were affected by the click of death, called so because the drives endlessly clicked when accessed, indicating the impending failure. 3.5-inch floppy disks can also fall victim to disk failure.
APPEND. Sets the path to be searched for data files or displays the current search path. The APPEND command is similar to the PATH command that tells DOS where to search for program files (files with a .COM, . EXE, or .BAT file name extension). The command is available in MS-DOS versions 3.2 and later.
