I have a IBM Deskstar 40 gig hard drive which has clicking noise on start up which stops after about a 30 to 60 second time out. BIOS does not recognize and it locks out other drives. I am willing to try anything to retrive data not including many hundreds of dollars to get professional help. I would even open up drive if heads are stuck. I saw one thread were drive was put in freezer for 30 mins. Does condensation not create problems? What are some extreme measures that I may try to retrive all or some data?
