              This report presents results from testing the Royal Canadian Mounted Police Hard-Disk Write Lock V0.7 (RCMP HDL) against the Software Write Block Tool Specification & Test Plan Version 3.0.
Abstract
              The latter specification requires that the top-level tool not allow a protected drive to be changed, not prevent the obtaining of any information from or about any drive, and not prevent any operations to a drive that is not protected. The test cases were selected from Software Write Block Tool Specification & Test Plan Version 3.0. All 40 test cases defined in the specification were applied to HDL V0.7. Test results are presented by mandatory assertions and optional assertions. The description of the testing environment encompasses the characteristics of test computers, hard disk drives, support software, and run protocol selection. When tested against the requirement that the tool should not allow a protected drive to be changed, the HDL V0.7 did not block all commands that could change protected drives in some test cases performed. Regarding the requirement that the tool not prevent obtaining any information from or about any drive, the HDL V0.7 allowed commands to obtain information from the protected drives for all test cases run, except for one command in the information category; the read drive type (0x15) command was always blocked on protected drives. With respect to the requirement that the tool not prevent any operation to a drive that is not protected, the HDL V0.7 always allowed any command to access any unprotected drives for all test cases performed.
