Hey Guys, take a look on this video:
https://www.youtube.com/watch?v=4LY3ZCmQZvcThis was done by a so called "Master", a professional for repairing things. He does not show, if the drive is working after his torture - I don't think so - but with his method he said that he repaired the drive and it's suggested for productive use. Without a clean room, poking the head stack like he doesn't know what he is doing and even leaving a fingerprint on the platter and cleaning it with a micro fiber cloth.
