Record the restoration process after SD card raw is repaired

A teammate's SD card, which was used on his mobile phone, was suddenly unavailable after several TXT e-books were imported into the computer. The symptoms were unrecognizable. On the PC, the card reader shows "Windows prompts formatting, but cannot complete formatting". After the attribute is displayed, the file system type is raw.

At first, I wanted to solve the problem in the simplest way, that is, using chkdsk, But I was prompted that the appropriate file system could not be found. At this time, it was preliminarily determined that windows would not have much hope to solve the problem. Later, I used diskgenius to view the SD card partition. fat16 is displayed in the information. In this case, the hardware is correct ., Of course, there is no problem. You can see the drive letter in windows ~ At this time, Google started to view the solution. I found several related articles and wrote them quite domineering. I directly used winhex to modify DBR. I went there. This is too high-end and I need to have a basic understanding of the storage structure of the disk. Later, we saw the raw
Data recovery. Learning.

Helpless, my laptop was powered off. I used my mobile phone to search for keywords and found that easyrecovery could be used for advanced data recovery. At this time, I saw a glimmer of hope. If the hardware is not damaged, you can simply format the data after it is taken. During the class this morning, it took another few minutes to look at the SD, CF, and MMC items.

When I got to the lab, I decided to try Linux first to see if I could mount it. The USB flash drive cannot be mounted to puppy Linux after being maintained by the system. In this case, you can only enter PE and select 2003 PE. Use "Easy to restore" to get the data back, and then use adds to format it directly. The problem is fixed.

Now, why is there a problem? Is it poisoned? There are some EXE files in the recovery process, but none of them are obtained. Thank you for your efforts in maintaining the disk. Thanks to so many posts and Google, you gave me hope.

Data recovery means a lot and will be explored in the future. Let's take a look at the driver of the SD card ~

I will learn from you more in csdn in the future. I used to be too inactive!
