Issuing a firmware info command but passing /dev/sda as a node returned expected result, so the drive is at least partially supported by the tool. Anyway, after inspection of the drive with DMM the point of failure appears to be at hardware level so the tool won't be much of a use. It's Micron M600 m2 disk btw. Thanks, Tom
