Case:
Customers should be damaged by the U disk after using the virus to use anti -virus software to kill the virus and cannot open it.
Solution:
After simply viewing, it is found that the offset this time is very different from the offset encountered before. The offset in the previous cases encountered was reflected in the secondary directory.EssenceIn addition to being inserted by the secondary directory, the start of the secondary directory is also modified and the file has not been changed.Set the solution for this situation: 1. First solve the problem of offset problems of the secondary directory (or more), remove the garbled part to restore the directory to the normal state 2, traverse all the directory in the logic disk(That is, the relationship between the dos command is commonly used) 3. According to the results of the directory, the wrong secondary directory address in the first -level directory is modified to restore the entire directory structure. Although it is only a 1G logic disk, the folder is the folderMany, at this time, you can use the script to complete such work.After the repair, all the directory restores normal (originally wanted to remove the deleted secondary directory, but abandoned due to changes in the FAT table).So far, the data recovery is complete.
