On your video, I never hear the brake release. After the drive comes to speed - about 5 seconds or so, you should hear a "clunk" as the brake releases and then the drive should start to seek. When it seeks, it will make very distinctive "squeak" noises.

I don't know if the lack of brake release is because you are only providing power to the drive, and not any data signaling from the Lisa.

I think this has been covered, but you can read about adjusting the brake in Pina's book.
