The specific process of data recovery in National Information Center.

I went to official website to check it out. If it is sent for repair, it is probably the following steps: 1. Customer service personnel receive the media to be repaired, register and fill in the data recovery worksheet of the National Information Center. You can know the progress of data recovery through the "progress query" on the data recovery website of the National Information Center; 2. Send the faulty medium to Guo Xin Data Recovery Laboratory, and the engineer begins to test the medium; 3. Within three working days after receiving the media, determine the final recovery price according to the failure type, damage degree and recovery time of your media; 4. If the media has hardware failure and needs to be opened, you must obtain your opening authorization. Without the authorization of the first article signature, Guo Xin will not further inspect the media; 5. The customer confirms the recycling price and decides whether to recycle; 6. After receiving the customer's quotation confirmation notice, start data recovery; 7. After the data recovery is completed, the customer service staff will notify to confirm the data. After confirming that the data is correct, go through the financial procedures, copy the data, and retrieve all the media sent for repair. Data recovery is over.
