Comment 1 for bug 1900623

Note - this was tested on real bare metal hardware and I can confirm that the fix results secure operation consistently succeeding as opposed to prviously (falsely) detecting failure to secure erase and then proceeding with a falback method. Speedup should be noticable as secure erasing an SSD drive takes under 15 seconds whilst zero-filling one takes 15-30 minutes.
For usual magnetic media, at least not both procedures are done so speedup should be at least 50%.
