Pedro, good to hear from you and sorry to hear about your problems. If I can try to make one helpful suggestion. I recently was able to get all my files off two completely dead HD's by doing the following. First, I pulled them out of the casing and hooked them up as external HD's (you can buy cheap kits for that) to another computer. Of course, the HD's were still dead, but I was able to copy all the files onto the new computer (or another external HD) using software I downloaded called "Power Data Recovery." I think it cost about $70 (there's a free trial version) but it's worth it. It has a couple modes, including one called a "deep scan" that takes about half a day but got me every single file back. And believe me, these HD's were dead, as in so dead my computer couldn't even find the drive letter without it. After my experience I would be of the opinion that if Power Data Recovery doesn't work then nothing would.
Anyway, just thought I'd lend my two cents. Good luck....
