My 2.5-inch hard drive recovery process:
Two 750GB Western Digital 2.5-inch USB3.0 mobile hard drives purchased in 2011 were used to back up data. One of them was damaged in November 2013.
At that time, the mobile hard disk was able to set a password, and the password could not be unlocked.
Referring to an English website, you can freeze the hard drive to restore the hard drive to normal!
I tried several times in the freezer to freeze at 18 degrees for more than 12 hours, and finally unlocked and deleted the password.
The hard disk can see the folder, file name, but cannot export the file!
(Note: The hard disk freezing method will damage the hard disk. Once the hard disk is removed from the refrigerator, it will form a thin layer of condensed ice water on the disk. The power running will cause the head or disk to be completely damaged.)
Ask the data recovery expert, listen to an expert said: It may be that one of the heads is broken, the master head is still intact, so you can see the file name and folder!
Taobao on the professional data recovery offer open hard disk box minimum offer 2000 yuan, and can not guarantee complete recovery!
So I watched a lot of videos on the youtube network to replace the hard disk head! I tried to use several old disks for the disassembly test and then read and write the test. I feel that there is no problem (of course, we must pay attention to the cleanliness of the dismantling environment)
I bought a repair tool (mainly a fixed head kit, matched with the corresponding hard disk, a set of aluminum alloy, a set of plastic, used to fix the magnetic head to avoid head sticking),
Finally, in early January 2014, the hard disk box was finally opened, and the head of another good hard disk was replaced with a bad hard disk (organ transplant)! Successfully recovered 217GB of data (it took 1 hour and 15 minutes to export the data)!
At present, the hard disk after the head change can still be used to back up some unimportant data. Disassemble the entire video, it is ready!
