I guess someone should post the usual disclaimer; i.e. that these firmware versions are unofficial hacks and that there is no guarantee that they will work.
Worse than that, there is the possibility that loading an unofficial firmware will trash your drive.
Also, even if the firmware does work, if your drive spontaneously dies at any time in the future, then you have invalidated your warranty by loading it. Unless you can flash the original firmware back, you could be in trouble.
OK so the chances are you will be OK, but beware of the dangers, that's all.
