Hitachi hard drive repair and recovery is a little bit different due to its firmware structure: The firmware codes stored in the Service area of  the drive; The firmware codes stored in the ROM chip and configuration data in the NV-RAM. There’re still  many Hitachi/IBM hard drives in the market and if you are going to enter data recovery field, you will undoubtedly meet a lot of Hitachi data recovery cases.
