A feature that'd really make it worth paying for the pro version of hddsuperclone, is the ability to work with non-standard sector sizes. You know those 520 byte EMC drives. If it could read those drives and migrate to 512-byte sectors on the destination, that'd really make it a miracle tool.
Another feature that I see is lacking, is the ability to zero fill the unread sectors after cloning is complete. It's not a problem is you're cloning to a blank drive or creating an image on a blank drive. But, I notice that it instantly allocates the full size of the image file created. So any sectors which aren't able to be read from the source drive may actually contain remnant data from deleted files on the HDD hosting the image, not actually from the source. So obviously that could be a security issue for anyone using this on a regular basis who doesn't understand this. Perhaps just a final wipe option (set on by default) to zero fill sectors on the destination which weren't read would be a good idea.
