Details

The CAST Key Reference Hard Disk (CKRHD) consists of a conventional mechanical hard disk drive of a specific capacity; the complete user addressable storage capacity which is present on the disk is prepared with known data. The purpose of the CKRHD is to allow users to assess the extent to which an imaging process acquires an image of the user addressable area of a hard disk drive.

This document provides information about the preparation procedure used by CAST in the creation of each CKRHD over the period July 2015 to April 2016. The procedure complies with the principles which are detailed in ‘CAST publication 063/16’. Users may wish to refer to both documents in order to understand the scope and utility of the CKRHD, how it was created and how it may be applied to local method validation tasks. Competent users may use this procedure to prepare their own reference disks in the style of a CKRHD if desired.
