computer hard drive system corruption data loss

Case:
A customer is a employee of the state -owned enterprise. It is mainly responsible for the shipment record in the company. It is usually protected by the computer, but I do n’t know why. The information recorded in the computer was gone last night.

Solution:
Because the data is important, it cannot be lost, so the gentleman first went to the Internet to find information about this. As a result, I found that there were really data recovery companies. I called to consult a few companies.Later, the engineer checked the customer’s hard disk and told the customer that the data lost can be retrieved, because the customer’s data is confidential.Therefore, a confidentiality agreement was signed and agreed to watch the whole process. The engineer used professional software to check the hard disk and found that the system program was wrong. Through manual calculations, re -corrected the program, proposed data, fix data, and resumed successful recovery.Essence
