HWB-comments-on-v1.doc 2 5/25/2004 1. Purpose The specification for hardware write block requirements [http://www.cftt.nist.gov/HWB- posted.pdf] was posted on the Computer Forensics Tool Testing (CFTT) website in November 2003 and users were notified that it was available for review. This document summarizes the comments received and the responses to the comments. The changes are reflected in http://www.cftt.nist.gov/HWB-posted.pdf. Comments are grouped according to common threads. The response follows each thread. In some cases, similar comments were omitted where it was clear that the response would address all of them. Notes to the Reader: Comments are written in italic font. Responses are written in Roman font. Where comments referred explicitly to specification sections in the HWB version 1.0 specification, responses also refer those sections. Where necessary, responses will also mention new section numbers to alert readers to modifications in the specification.

Comments 2.1 Thread: Section 5, Item 5 – Scope – Non-hostile environment It would be quite simple for a malicious program to permanently cause harm to a drive if it were built to match the current specification. As such, we would suggest that item 5 be dropped or changed to reflect this reality. Response: Section 5, Item 5 – Scope – Non-hostile environment The intent of this section was to communicate that the user of the device was not trying to circumvent the proper function of the HWB device. Several sections in the specification have been modified to more explicitly express this intention. Purpose (Section 2): This document defines functional requirements for hardware write blocker (HWB) devices used in computer forensics investigations. It does not define requirements for protecting storage devices from misuse, either intentional or not intentional.” Scope (Section 5, Item 5): “Preventing misuse of the storage device is outside the scope of this document.” 2.2 Thread: Requirement to always allow non-modifying operations We strongly disagree with the statement: “a HWB should not allow modifying commands to be transmitted to a storage device and should allow non-modifying commands to be transmitted a storage device”. Response: Requirement to always allow non-modifying operations
