Case:
After the customer’s hard disk was shut down normally, the hard disk was not recognized the next day.
Solution:
The power connection is the F -class on the terminal. Most of this phenomenon is caused by the problem of magnetic heads. Only the opening of the magnet was opened. After finding a model, the place of production is the same, and the production date is similar. Open the market in the ultra -net table, carefully remove the magnetic head, change to the customer’s plate, close the lid, power the card to find the card to find the card The sound of the card, open the cover again, take out the plate with the opening device, put it in a relatively strong place, and check it carefully. No scratch is found. After the cover was powered on, I found that the sound of the Kaka was caused by the magnetic head. What was the reason why it hadn’t come 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 fiddled with my hands and found that it was normal. Put the magnetic movie again. Boring and helpless, I held the screwdriver in my hand to insert the small hole on the magnetic movie when I found the magnetic movie and the magnetic movie underneath. There is a certain space, you can move back and forth … Why is this? Magnetic movies can move, do I think that after changing my head, the positioning of the magnetic movie needs to be adjusted, so I re -fixed the magnetic movie above and passed the power again. It turned out to be this problem. The magnetic head search began, and the reading data is normal.
