Case:
Customers took a 320GB WD hard disk, because the sudden power disconnection caused the hard disk to not format, and many documents and documents in the hard disk were stored in the hard disk.
Solution:
First of all, use Winhex analysis. Listening to the customer that there is only one partition before the computer says that the 0 -sector MBR is normal. The number of unknown numbers in the 63 -sector DBR appears.Suddenly, DBR lost, and the loss of NTLDR.So copy the backup DBR of the last sector to 63 sectors, regardless of the partition after 63, although the partition cannot be opened, at least in Winhex can be seen.If you want to open the partition, you have to copy the seven sectors after DBR. I find another NTFS partition, copy the 7 sectors behind DBR to the behind DBR of the fault drive, restart, the data is intact and non -destructiveEssence
