Although it has a name DD in it, it's missing one usefull feature, and that's writing to DISK/VOLUME from some file. That way we could use it for backing up GPT Headers and tables, and then restoring it.
Another thing, parameter "-Offset" should really be renamed to "-Skip" (or use it as a completely new parameter), and counted in blocks ( based on size of the block).
Let's have a medium sized 4TB disk, and we want to backup very last sector ( Backup GPTHeader). That's a large number, and mistakes could be made counting in bytes. Also, since disks are block based, we really should be thinking in blocks, not bytes.
