Case:
The customer wanted to copy the photos in the digital camera last night. Just a few of them, the progress was not moved, forcibly closed it, and then opened it to prompt formatting.
Solution:
Initially believed that the DBR was lost, opened it with Winhex, and the 0 sector had a partition table, showing that there was only one partition, and the relative number of sector was 233. Therefore, the 233 sector should be DBR and jump to 233 sectors.It is 0 and last 55AA, which is determined that DBR is destroyed.Move a few sectors down and discover the FAT table. The format is FAT16. The FAT16 does not have a backup DBR. First use Winhex to make a mirror, then format the flash memory, extract the normal DBR copy to the image, and then restore the image data.
