Western Digital 1T enterprise hard drive is very slow to read data_Important Data Recovery

Case:
Customers are a program developer with good data security and backup data awareness. Through the phone, the hard disk learned that the hard disk is a western -digit hard disk, which is mainly used as a backup disk to use it for many years.During the copy of the data, it was found that the replication speed was very slow. Although the small files were slow, they could be copied. Large files (more than 10 trillion files) could not be copied and accompanied by the system that could not be responded, so the phone for helping the data recovery center.

Solution:
The engineer of the Data Recovery Center is also worried about the security of the information accumulated for many years!Because in the previous recovery case, the possibility of bad sectors of this model of enterprise -level hard disks is relatively small, which is generally caused by a certain magnetic head in the magnetic head component (a total of 6 magnetic heads).Very bad.After communication and understanding, the customer sent the hard disk to our engineer test and found that there was a problem with the No. 3 magnetic head.After explaining the situation to customers, start to restore the matter.1. After the spare part was received for help, I was very anxious. The library was matched to the same hard disk of the same model.2. Do the appearance of the data disk and spare parts.3. Replace the magnetic head component in the dust -free room.4. In the PC3000 For UDMA professional tools, the hard disk is used to find a normal disk, and the professional module is tested and repaired the wrong firmware extraction data. There are more than 6 million files.Intersection
