Case:
The laptop of customers in Guangming New District has been used for more than 5 years. It was used normally yesterday. Today, it was suddenly unable to turn on it. The laptop could not recognize the hard disk.
Solution:
First use UDMA to detect the fault hard disk. After the power is powered on, I hear the sound of a knocking in the disk, and try to power on multiple times.The magnetic head problem, because there is no preparation of the same model at hand, and the customer is more anxious. By comparing a comparison, a hard disk parameter and fault disk of ST3160023AS are relatively similar.In order to prepare the disk. After replacing the magnetic head, it is found that it can be identified normally. The information under the instruction is normal. The others are relatively simple.
