Editing File system (section)

=== Data integrity ===

A file system typically ensures that stored data remains consistent in both normal operations as well as exceptional situations like:
* accessing program neglects to inform the file system that it has completed file access (to close a file)
* accessing program terminates abnormally (crashes)
* media failure
* loss of connection to remote systems
* operating system failure
* system reset ([[warm reboot|soft reboot]])
* power failure ([[hard reboot]])

Recovery from exceptional situations may include updating metadata, directory entries and handling data that was buffered but not written to storage media.
