Case:
The client sent a 2.5 -inch laptop hard disk, saying that it is not recognized during the system, but it can be recognized and unavailable after restarting.
Solution:
After the engineer’s test, the hard disk was found to have a common problem with the Seagate hard disk. After detecting a certain bad lane, the whole inspection became a bad channel. Without re -power the hard disk, the hard disk could not continue to be recognized.The customer talks about the two -discoscope of the disk and has very important corporate documents under the D/E, hoping to help restore the data as much as possible.The engineer first repaired a hard disk according to the Seagate’s illness, clearing Smart, G table, rebuilt the decoding table, and tested the hard disk again. In the case of the bad duct, it will not report an error, and it can continue to be tested.Try to use UDMA for a full -scale image, but I found that the mirror speed is really slowly described as a dust -free description. It also uses UDMA to perform a magnetic head test. It is found that the three magnetic head reading and writing conditions are not much worse.It is not recommended to replace the magnetic head. After all, the original magnetic head has not been damaged, and it will not scratch the disk surface. If the magnetic head is changed to change the magnet, the risk is relatively high. You can only continue to read and write the image with the original magnetic head.After a few days and nights, the full mirror was finally completed, and the data was very complete.
