Case:
Customer computers cannot recognize the hard disk.
Solution:
The hard disk was detected, and it could not be reset after power -on. The instructions stagnated when the master information was about to appear. At this time, there was a slight knocking sound in the disk.Power -powered and electricity sometimes prompts the app to load an error prompt.During the treatment, the magnetic head problem was processed. After the opening of the magnet, the failure was still scratched by the plate firmware area.After receiving this disk, it is roughly judged that there is no problem with the process of changing the head. There are two possibilities that may be the scratching of the plate firmware area that the module cannot be loaded, and the disk cannot be ready.The group or motor is unstable. There is currently no corresponding solution for the current one. The simplest is the latter replacement circuit board.After replacing the circuit board, the failure is resolved, the magnetic head reset is normal, and the information under the instruction is normal.Entry DE has been able to read data, and after checking the data with users perfectly recovers.
