I know this sounds nuts, and I thought so before I tried it, but put the HDD in a plastic bag and place it in the freezer overnite. I have tried this with 5 drives, and was able to retrive data off of 3 of them. I build computers out of donated parts for people who can not afford them, and a tech friend told me this. I called him nuts, untill I tried it. what have you got to lose?
