Diagnostic Port Locked

To fix above patient drive, the user used DFL Seagate hdd repair tool to backup rom, generate unlock rom, write unlock ROM, power off and on, send unlock key, backup important SYS files, clear g-list, regenerate translator, etc.

After fixing the firmware area, the users tested the data area and found there’re some bad sectors in the front, the middle and ending parts of data areas were accessible.

The user set up head map, edited the LBA range to image the patient hdd by heads within DFL-DDP data recovery equipment and finally most data was recovered, only some system files were missing which are not important at all.
