Case:
A 16GB U disk for a customer has been using it for almost half a year. Suddenly, the disk is found.
Solution:
This situation is likely to storage ICs, so the U disk is opened. After testing, it is found that the U disk uses Micron’s storage IC, and there is no virtual welding.Still the failure of the storage IC, just have this type of circuit board on hand. After changing it directly, you can find it but still the same problem. Try to remove a storage IC and find that you can identify and browse the data normally. It seems that a piece of IC is broken.EssenceHowever, if you think about the storage principle of the U disk, in general, the main control program should initialize the two ICs as one piece.Because the amount of data of the user is small, only 60 m, after verifying the data with the user’s verification of 100 %, the data is successful.
