Case:
The computer hard disk used by a leader of the General Office of the Provincial People’s Government suddenly failed, because the data confidentiality issues must be recovered.I have invited two people to see it before. First of all, a company that was repaired. After seeing it, there was no way to start, so I introduced the person who resumed the company.After the test, it was said that the device did not take Qi to go back to get the equipment, and the result was not back. (It is estimated that there is no professional device to recover on the spot, and the data is very important.Essence
Solution:
Finally, after many parties to inquire about the call of the data recovery engineer, the data recovery engineer first asked the fault phenomenon and hard disk model of the faulty hard disk on the phone. Then I took the only PC3000 UDMA+Data Extractor data recovery device in the city at the time to come to the Provincial Government General Office. The failure of the hard disk is basically the same as before: the first is because the hard disk appears in the hard disk, and then the current hard disk has a smart function, which automatically adds the bad sectors during the use of the discovery process to the hard disk firmware area in the hard disk firmware area A bad channel table G-List (G-List, also known as the list of growth defects, is designed by hard disk manufacturers to hide a small amount of bad sectors that appear during the use of hard disks, so that the hard disk will not return because of several bad sectors. The factory is maintained), but the capacity of the G-List is limited, and often can only record a maximum of hundreds to more than one thousand sectors. Later, the hard disk is too bad. After writing the G table, the hard disk firmware is wrong. It is easy to handle the cause of the fault. First, use UDMA to repair the hard disk firmware, and then use the data extractor to directly extract the hard disk data to the hard disk provided by the customer. Speed, less than 3 hours of data recovery.
