Case:
Customers use a 500GB West Digital mobile hard disk to copy a large file. Because the user is too long to make the USB interface because the user is too long, then when you connect to the computer, you cannot browse the logic disk.
Solution:
When opening in Disk Manager, it prompts “file or directory corruption”. A typical metafile error phenomenon, this situation is likely to be caused by an MFT metafile error or an INDEX index error. Specifically, which one needs to be analyzed to be able to Certainly. When entering WINHEX to open the logical disk, it prompts “connot open mft *****”, and the MFT metafile cannot be opened. After entering the logical disk, it is found that there is no MFT chain. At this time, the DBR is normal, and the MFT starting cluster is obtained from the DBR parameters and locates the past. Later, it was found that the metafile MFT was damaged, and after careful inspection, it was found that the first three metafiles were offset. So copy and generate new files to study these MFTs and found that they were normal metafiles, and they returned to normal after writing back directly.
