Case:
The engineer of the Data Recovery Center received a hard disk with a hard disk, the secondary opening data of the hard disk restored 5K500.B-500.Preliminary testing and finding that hard disks are physical faults.Is the hard disk PCB circuit board disconnecting and analyzing whether the hard disk BISO is primitive. Check out the position of the data area and firmware area of the hard disk found that the BISO finds the hard disk.
Solution:
Because this hard disk has been opened, the first step needs to clean the dust inside the hard disk.Use a dedicated hard disk to clean the liquid. After an hour of continuous fighting, the plate is cleaned up.After testing by senior engineers, the diagnosis was damaged by the hard disk due to damage to the power module.In the data recovery of the special 100 -level cleaning room, the engineer replaced the same type of magnetic head, then used the PC3000 to test the parameters of the SA area of the hard disk, and wrote the matching firmly prepared by the spare parts.After testing, the hard disk can be recognized, enter DE, copy the important data of customers.
