British HMG IS5 (Baseline) (1 pass)
Your data is overwritten with zeroes with verification
British HMG IS5 (Enhanced) (3 passes)
British HMG IS5 (Enhanced) is a three pass overwriting algorithm:
first pass - with zeroes,
second pass - with ones and the last pass with random bytes (last pass is verified).
