So far 40GB have been already rescue... ddrescue still saving my files, it's a very good recovery tool!!!
As promise, once all done, I will post the video of the platter transplant and also an step by step about ddrescue. I spent some time to find out how to set and use ddrescue properly.
But for now, please find my post conclusion:
Lot of people (like in this thread) will tell you to not open your drive and send it to a profesional, the same people who own or work in this kind of company I guess. The ones will ask you 2000-3000$ for recovery your most precious souvenir. For me, so far, this industry and the ''clean rooms'' are a scam, using the distress of poeple to make money, and keeping all them knowledge as secret to make sure it will be no other way to go to them if you want recover your data. Anyway, I fully support Scott Moulton (google is your friend), as he said if you have money and you don't want to take any risk of loosing your data go to a recovery company, is the best choice. But if you no that rich, let's try to do it by yourself in most of the case you will recovery your data without big pain (swap PCB, or even just run ddrescue). It's nothing really magic in an hard drive. It's lot of poeple like Scott Moulton posting videos and tutorial to help people who can't pay such a price to recover them data and souvenir.
Special thank's for Fzabkar, the only one in 27 post of this thread who try to help giving some ideas and positive recommendation, instead of said (like the 26 other ones): you crazy! if you just open it just for a sec all your data will be lost... come on guys, wake up! be realistic, hdd in 2010 are more robust then it was in 1990's. If you own or work in recovery company, be honest and just said: bring it to me, I want your money!
Again I invite all of you to have look on the videos of Scott Moulton who is an recovery data specialist then you will know all the true about this mascarade industry. Start here
http://www.youtube.com/watch?v=vCapEFNZAJ0 Important: don't open WD multi platter coz the top of the drive is what keep the platter aligned, and don't try to tranplant platter in a multi platter hdd. This apart your welcome to do anything on an hdd by yourself...
Have look on internet, on videos, etc... before do anything on your drive, be patient, and learn ou to do. Even if is nothing magic on hard drives, is a lot of common sense to consider if you gonna open it. Do it on a room as clean as possible, no fan near to your table, don't put your finger on the platter, don't try to clean the platter is not a pan, don't play much with the head, etc...
