collection of tools for forensics analysis on volume and file system data

 The Sleuth Kit (previously known as TASK) is a collection of UNIX-based command
 line file and volume system forensic analysis tools. The file system tools
 allow you to examine file systems of a suspect computer in a non-intrusive
 fashion. Because the tools do not rely on the operating system to process the
 file systems, deleted and hidden content is shown.
 .
 The volume system (media management) tools allow you to examine the layout of
 disks and other media. The Sleuth Kit supports DOS partitions, BSD partitions
 (disk labels), Mac partitions, Sun slices (Volume Table of Contents), and GPT
 disks. With these tools, you can identify where partitions are located and
 extract them so that they can be analyzed with file system analysis tools.

 This package contains the set of command line tools in The Sleuth Kit.
