Western Digital 320GB hard drive unreadable data recovery case

Case:
After the financial computer of the customer company, after the hard disk had a problem, the company’s network management searched the online search solution and downloaded some partition software reconstruction partitions. The data still did not recover.So repeatedly reconstructed operations, and tried multiple software, and eventually no fruit, recovered in our center.After receiving my computer, the computer immediately became slower. The operating system lasted 10 minutes. After entering the fake death machine, it was difficult to enter the disk management. The hard disk display could not be read.

Solution:
The preliminary judgment is the hardware problem. When it is connected to the UDMA detection, the hard disk can be ready, and the detection firmware is normal. Because it is good at software recovery, it is processed according to the software failure. After receiving the computer, open it with PQ, prompting disk errors. Then open it with diskgenius. As soon as you enter, it is prompted to overlap the partition. There are 7 partitions (primitive 4 partitions), with a total of about 30 overlap partitions. Delete all of them with diskgenius. Hang from the disk to the computer again. The hard disk has been identified by the operating system and has not been read. Based on a simple recovery process from simple to complex. Scan the lost partition with partition software, and when scanning to about one third, 40-50 partitions appeared. After scanning, 255 partitions were found. Software scanning has not achieved the purpose of recovery, because the partition information is too chaotic, and it is normal to scan so much. You can only use Winhex to manually analyze, and search for the end label of 55AA according to the original partition size described by the network management. At about 10 minutes, the recovery of all partitions will be restored. Winhex traverses the physical disk and opens all the partitions. The directory of each partition includes a complete file name. Preview a large Access database, which is opened normally. The regional recovery is successful, and the data is perfectly reproduced.
