  Annotation: This report presents the testing results for the Digital IntelligenceFireFly 800 IDE (FireWire Interface) write blocker against the performance criteria for a hardware write block (HWB) specified in Hardware Write Blocker Assertions and Test Plan Version 1.0.
Abstract: A HWB is a device that is intended to prevent the alteration of any data on a storage device protected by the HWB. One of the performance criteria specified in the Hardware Write Blocker Assertions and Test Plan Version 1.0 is that the HWB shall not transmit a command to a protected storage device that modifies the data on the storage device. In the testing of the Digital IntelligenceFireFly 800 IDE, the device always blocked any commands that would have changed user or operating system data stored on a protected drive. Thus, this performance requirement was met. A second performance requirement is that an HWB device should return the data requested by a read operation. For all test cases run, the HWB device always allowed commands to read the protected drive. A third performance requirement is that an HWB device return without modification any access-significant information request from the drive. The HWB device being tested met this requirement, since in all test cases run, it always returned access-significant information from the protected drive without modification. The fourth performance requirement is that any error condition reported by the storage device to the HWB device shall be reported to the host. For all test cases run, the HWB device always returned error codes from the protected drive without modification. This report provides information and pertinent data on the test case selection, observations, the testing environment, and test results.
