Case:
Customers send a ST320GB hard disk, saying that it cannot be recognized, the hard disk has no response, and the hard disk has collided.
Solution:
Looking at it, I found that the motorka died, the plate was scratched, the motor was forcibly dialed, and the power can be transferred. The PC3000 can be recognized. The recognition is relatively slow.The more troublesome, I had to change the magnetic head. After the replacement, I used PE to make a data copy. Pray that the magnetic head is not broken. Eventually, 80%of the data was restored.
