For the IOMagic box, just look for the 8x DL logo within the red 16x circular imprint. That will be the 1655. If it doesn't have the 8x DL logo, then it's the old 1625. You can request a black faceplate from IOMagic: firstname.lastname@example.org, give them the drive make, model, & firmware version, as well as your mailing information. If they don't have it, then you'll get an email indicating that. Otherwise, you should see it within a week or so in a padded envelope. That's how I got my 1640 (IOMagic box) faceplate.
