U disk prompts "Disk is not formatted" What to do

I do not know if you have encountered this situation: when using a USB flash drive or other SD card, may be due to improper operation "Disk is not formatted" The prompt box, when you encounter this prompt, it shows that the trouble is big, because if the formatted data will be lost, if you can not extract the data and can not be taken out, I really want to cry. In fact, the U disk prompt is not formatted due to the damage of the DBR of the disk, and now you can use the "Winhex" tool to fix without formatting. The reason why the disk is not formatted is because the DBR of the disk is damaged. Each disk will generate a DBR and a backup DBR after formatting. Both are the same. When the DBR is damaged, it can be restored with the backup DBR. . The DBR is in sector 0, and the backup DBR is in sector 6, so we have to restore the backup DBR of the sixth sector to the DBR of sector 0. The disk is not formatted.
