This report presents the results from testing the Tableau Forensic IDE Pocket Bridge T14 (FireWire Interface) write blocker against "Hardware Write Blocker (HWB) Assertions and Test Plan Version 1.0."

Abstract

Testing results showed that the Tableau Forensic IDE Pocket Bridge T14 by Tableau met all of the required standards for a HWB. One testing standard requires that a HWB device not transmit a command to a protected storage device that modifies the data on the storage device. For all test cases run with the Tableau Forensic IDE Pocket Bridge T14, it always blocked any commands that would have changed user or operating system data stored on a protected drive. A second testing standard is that a HWB device should return the data requested by a read operation. For all test cases run, the tested HWB device always allowed commands to read the protected drive. A third test standard for a HWB device is that it should return without modification any access-significant information requested from the drive. For all test cases run, the tested HWB device always returned access-significant information from the protected drive without modification. A fourth test standard is that any error condition reported by the storage device to the HWB should be reported to the host. For all test cases run, the tested HWB device always returned error codes from the protected drive without modification. Test descriptions, tables, and figures are provided.
