Data recovery mobile hard disk prompts I/O device error

Case:
The customer’s 320G mobile hard disk is used for more than a year, and the hard disk is divided into two partitions.Recently, after the mobile hard disk is connected to the computer, the reading disk is very slow. Some data can not even read, and the computer often crashes.Customers use CHDISK to repair the mobile hard disk, then insert the computer back, and the mobile hard disk prompts I/O equipment errors.

Solution:
First of all, after getting the hard disk, I wanted to directly extract the data of the mobile hard disk, but found that the mobile hard drive’s bad duct was very serious. The operation of the customer CHDISK caused the problem to be more serious, and it must be opened to recover.After the customer’s consent, the engineer conducted an opening operation under the dust -free room. In less than a day, the mobile hard disk data was read smoothly. After confirming the customer, the customer’s very precious photos and some information were successfully recovered.
