Case:
I accidentally touched the moving hard disk during a hard disk while using it, and then used to find that the hard disk read the data of the data was significantly slowed down.
Solution:
After receiving the hard disk, we picked up the PC3000 UDMA. Through the detection, I found that there was a problem with the hard disk firmware. There were still many regular bad sectors in some areas.We replaced the SATA compatible circuit board, repair the firmware, then the full mirror, and then decrypted, and finally successfully restored the customer’s 98%data.
