I just received shipping confirmation and a tracking number...probably be a few days before I receive it from cross country. I'm pretty surprised they are honoring the price. To the best of my knowledge, Compgeeks is a relatively small, hands-on operation. Seldom do pricing mistakes go unnoticed (or honored) in these situations.
With regard to the firmware, it's probably easy enough to change the ID string in the binary code with a hex editor (so it matches the HP string). However, I think that would only allow you to use Plextor's firmware update, not actually modify the ID string on the drive. I'll look at it a little more closely once mine arrives.
Best regards,
Floyd
