Case:
Customers are Windows7 operating systems, Hitachi 7200 rpm 320GB laptop hard disk; use PC3000 UDMA to detect hard disks, cannot be recognized, power -on detection, disk body abnormal noise, which is a magnetic head damage failure.
Solution:
The engineer first disassembled the hard disk in the dust -free room, and used the SAP separated from the ROM of the original hard disk to match the magnetic head in the same type of spare parts.Use a well -matched magnetic head to replace the original damaged hard disk. After the replacement is completed, connect to the PC3000 for UDMA, and use the PC3000 for UDMA to perform a complete sector -level image on the hard disk to maximize the bad sector data.Because the bottom layer of the hard disk uses the Bitlocker encryption of the Windows system, the encryption volume has high requirements for data integrity. It cannot directly mount the partition to restore the data. You need to analyze the BitLocker encryption volume structure at the bottom layer of the file system, and then use North to use North to use NorthThe internal tools independently developed by the Asian Data Recovery Center will complete the encryption volume from the bottom layer of the file system.After the decryption is completed, fix the final data.
