Case:
The client said he was designing graphics with AutoCAD software, and the computer suddenly restarted automatically.After restarting, you cannot enter the Windows operating system.Later, I found the company’s computer administrator for testing, saying that the hard disk was damaged, as if it was said that the sound of the hard disk had a mile la la la la la la, and the computer host had no human collision.Mainly rescue the DWG design file in the hard disk.Customers find a data recovery center through the Internet.
Solution:
The engineer of the data recovery center first detected the hard disk circuit board, and did not find any failure such as burning and overcurrent.According to the information provided by customers, combined with the experience of the ST3160811AS model in the past, the preliminary diagnosis should be caused by firmware or magnetic head problems.The engineer of the Data Recovery Center used professional equipment PC3000 UDMA COM to access the hard disk and found that the hard disk has a search signal as soon as possible.Through the professional equipment PC3000 UDMA read and write firmware module, test the magnetic head, and find that the magnetic head reads and write is normal. The hard disk firmware is repaired through the terminal instruction, combined with the PC3000 UDMA de mirror.The full mirror is complete, the data recovery is 100%recovery, and the customer accepts data satisfaction. So far, the data recovery is successful.
