Case:
The customer used the normal shutdown for the last time, and then could not enter the system and could not recognize the hard disk.
Solution:
The preliminary analysis should be a common problem that belongs to the ST11 generation disk.After testing, the magnetic head was found in 3K, but it was normal to determine that the magnetic head reset was judged from the sound. The disassembly of the circuit board was connected to the XLY terminal, and it was ready to be ready.So the circuit board is connected to the level 2 and then shut down, and then the circuit board is connected to the disk body, then the instruction is turned on to turn on the motor, clear the Smart and G meter, and the power is replaced.Unexpectedly, because the capacity is still 0, then the capacity is only recovered in XLY, so far the data recovery is successful.
