Abstract: Disclosed file system management techniques can augment and/or enhance a file management system (e.g., a conventional file system) provided for organizing data stored in computer readable storage medium (e.g., a HDD). Data and metadata can be written to a file system space of a file system without using a file management system and without incorporating the data into the file system. However, the metadata can include information allowing the written data to be (later) incorporated into the file system and without having to use the file system, thereby allowing write performance to be enhanced. Generally, metadata can provide additional information including data (e.g., integrity data) that cannot be provided or efficiently provided by the file management system to augment a limited or reduced file system. Integrity data can be especially useful for error recovery (e.g., after a system failure).
