Data Recovery from a Hitachi HDS722020ALA330 with Bad Reading Heads and Lost NvRam

Drive is from  a professor with tenths of Postdoctoral and Ph. D students’ research work. Hard drive was clicking. Data recovery attempts had made it worse and NvRam was damaged. Data Care Clinic received the drive, NvRam cannot be read by PC 3000 Express as well as several professional programmers. After NvRam restoration, drive can be detected fully and can read about 1 TB data, bad media took out 2 of the 10 heads. Head change is successful, after adjustments, Data Care Clinic gets a full clone. All sectors have been read OK.
