Case:
The customer’s 250G hard disk, because there is a bad duct that cannot enter the system. In order to restore the data, the customer uses the tools to repair the hard disk for the hard disk, but it still fails. The hard disk has four partitions. Now the customer needs to restore the original eDisk and f data data.
Solution:
First of all, access to the PC3000, and found that the hard disk can still be recognized. There are many bad channels for scanning and found that the hard disk has a lot of bad disks, especially the system disk C drive. Originally, I wanted to make the data of the E drive and F drive.It was caused by the customer’s own repair of the bad sector, so he had to do a full copy. Because the customer only needs to do the data in the two partitions in the back, so the data of the rear half is made first.When the data is almost done, find DBR through Winhex to determine the exact position of the E disk and F drive. It is strange that a DBR has not been found. After a long time of analysis, I found that the data of the entire hard disk was shifted backwards 16 words.The festival is the first time that this kind of problem has been encountered, and the specific reason for this situation is unclear, so the files where the E and F disk are located are re -generated and the data is issued again.
