If you want to recover the data, you will have to have the drive worked on by a data recovery specialist. Do not try to use the drive any more, or it may become (more) damaged. Data recovery is expensive, usually requiring the disassembly of the drive in a clean room so that the platters may be removed and the data recovered.
