Never repair a drive containing critical, unbacked-up data. Use a tool like (Linux) or HDDSuperClone to create a bit-by-bit image of the Hitachi drive onto a healthy storage device. These tools are designed to skip bad sectors quickly without wearing out the failing drive. Step 3: Run a Low-Level Sector Remap
If DFT encounters bad sectors, it prompts the user to perform a "sector re-allocation." This instructs the drive's internal firmware to swap out the damaged sectors with healthy spare sectors from the drive’s reserved area. hitachi hdd repair tool
