Case:
The client said that the hard disk was removed from the laptop computer. Because of his own work, he often used a laptop computer, which may be used for a long time, which caused the laptop to run slower and slower.I think it should be a systematic problem. I found a friend to help reinstall the Windows7 operating system. The installation time feels a bit long, but it is successfully installed.After that, I installed other software used by the office, and the laptop was good.The next morning, I turned on the laptop and found that the system was super slow. I helplessly forcibly pressed the power button to restart. I found that I couldn’t enter the system.It was found that the hard disk was damaged by a friend.Mainly rescue Word and EXCLE files.
Solution:
The engineer of the Data Recovery Center first, based on the information provided by the customer and the experience of restoring Toshiba hard disk in the past, is initially estimated to be caused by the failure of the firmware problem or magnetic head problem. Then use the professional equipment PC3000 UDMA to detect that the hard disk is found to be complete as soon as it is powered on, but after finding the road, it continues to make a giggle and giggle sound. The engineer of the Data Recovery Center first uses the PC3000 UDMA to repair the firmware of the hard disk. However, it is found that during the hard disk detection of bad sectors scanning, it is slower and slow. The diagnosis is caused by a magnetic head, or the magnetic weakening of the disc surface. By PC3000 UDMA split head mirror, and then find the matching magnetic head through the accessories library, cooperate with the internationally professional magnetic head replacement tool, perform a magnetic head replacement on the level 100 dust and clean platform, and continue to use the PC3000 UDMA image. The mirror is smooth. There is a position with data at the bottom. The mirror is particularly slow, and there are many bad sectors. It is the same situation that several magnetic heads are replaced in a row. The magnetic weakening of the disc (because it is the side of the laptop hard disk contacting the laptop motherboard. After a long time of high temperature baking, the magnetic properties of the disc will become unstable, slowly weaken the magnetic nature), resulting in slow mirrors and many bad sectors. After a few days of repeated mirrors (really not easy), the data can be finally produced, and about 9 successful data are restored. Finally, the customer’s acceptance data is satisfied and the data recovery is successfully completed.
