Case:
A company IBM ThinkPad T61 laptop cannot start the system, and there is a click when turning on.The hard disk was removed and hung in the mobile hard disk box.
Solution:
After testing, the magnetic head of the western hard disk was deformed due to the long use time, which caused the sound of click.The engineer uses the same type of hard disk for the opening of the magnet. Because the magnetic head matching of the Western number is more difficult, the accurate match is successful, and the fixedware information is updated. The hard disk can be identified normally, and then the data is successfully extracted under the Western Digital platform.
