Media information:
Samsung hard drive 80GB model is HD080HJ SATA interface
Fault description:
Recently, I received a Samsung hard disk from a customer. The customer described that the hard disk suddenly crashed. Later, the power was restarted. After that, the hard disk could not be accessed. Only the sound of the chassis was heard.
Fault detection and judgment:
After the engineer took over the hard disk, he started the test through a professional device and found that the hard disk had abnormal noise. Judging by experience is definitely that the head is damaged. It is necessary to open the corresponding magnetic head assembly to solve the problem.
Data recovery process:
After communicating with the customer, the customer agreed to recover. The data recovery engineer transferred the spare hard disk of the same model from the spare parts library. After opening the disk in the 100-level open clean room, the faulty hard disk was found to be 4 heads, but the spare disk was 2 heads. . Data recovery engineers have learned from their hard disk data recovery experience for many years that this 80G hard disk is definitely the second head, while the fault disk is four heads. Therefore, it is speculated that this failed hard disk was previously a 160G disk. A disk that may be modified by the manufacturer. The spare parts of 80G are definitely not usable. After re-ordering the same type of 160G hard disk head from the spare parts library, we have obtained the following information on the UDMA.
We see the model, SN, firmware version, and the capacity is all normal. Scanning sectors is very good. Customer data is fully recovered through UDMA tens of minutes of mirroring.
Data recovery results:
Hard disk data 100% recovery
Advice to customers:
Pay more attention to data backup when using older or longer-life hard drives. The old disk is used for a long time, and the magnetic head is gradually aging. If there is a problem with the hard disk, stop the power-on operation immediately to prevent the surface from being scratched and causing secondary damage. Do data recovery to find a professional and regular data recovery company to ensure complete and rapid data recovery.
