Case:
Customers respond to computers.
Solution:
The power connection is the F -level on the terminal. Most of the phenomenon in the hard disk of ST is caused by problems with the magnetic head. I don’t know much about the specific reasons and principles. I only know that basically the head is bad. If the customer wants the data inside, it only has to change the magnetic head. After finding a model, the place of production is the same, the production date is similar. Open the cover in the ultra -net table, carefully remove the magnetic head, and replace it to the customer’s disk. Follow the lid and power to find the Kaka. Essence The sound of the disk will not be a problem. Open the cover again, take out the plate with the opening device, put it in a relatively strong place, and check it carefully. What is wrong, so I did n’t try it on the plate, and I found that the sound of the kaka was caused by a magnetic head. What was the reason why I did n’t go to the plate? I looked at the direction and movements of the head operation seriously when I was powered on, and found that it seemed that the magnetic head could not cross an obstacle. Placing back and forth at almost 2mm distance, that is, the information on the plate was unable to read the plate. So I then opened the permanent magnetic movie posted on the magnet, and I didn’t find anything because I stuck the magnetic head on the head when I changed the head. I put it on my hand and found that it was normal. I was very puzzled. I put the magnetic movie up again. I suddenly found that there were two small holes on the magnetic movie. What did the two small holes do? It should be useful. Otherwise, the manufacturer won’t be bored enough to play two small holes to play, so I wondered how the manufacturer was on this magnetic movie? Boring and helpless, I held the screwdriver in my hand and inserted the small holes on the magnetic movie when I was swinging on the left and right. I found that there is a certain space between the magnetic and lower magnetic movies. Why is it? Magnetic movies can be moved. Do I think that after changing the head, the positioning of the magnetic movie needs to be adjusted, so I re -fix the above magnetic movie above and call it again. It turned out to be this problem. The magnetic head search began, and the reading data is normal.
