Hitachi local disk G table problem data recovery case

Case:
The customer’s laptop was only used for half a year. It was unable to enter the operating system when it was used yesterday. It was found that it was a hard disk problem. Now it is necessary to propose important data in the hard disk.

Solution:
The notebook uses a Hitachi hard disk with a capacity of 640GB. Hitachi hard disk has a more typical firmware failure, that is, the problem of the G table is reported to cause the hardware data to be unable to read.First use the PC3000 to detect the hard disk. You can recognize the hard disk normally. When scanning the hard disk, you can sometimes scan normally. Sometimes the scanning speed is very slow, and sometimes scan the full error.From the test results, it can be determined that the hard disk should be a bad sector and there is a problem with the firmware.For a typical firmware problem such as Hitachi, you can ignore the data directly, and the data is successful after many attempts.At this point, the data is successfully recovered.
