It might/should work, but it depends on a few things, so don't start writing to that disk with MBRtool just yet. If you'd be willing to take a look, download and install HDDscan (http://hddscan.com
). Look for the "identify information" screen and check how the disk reports its sector size. If that comes back as 512 the disk handles the conversion internally, which means that MBRtool should work as expected. Please let us know.
