Can the data be recovered after the USB disk is not recognized?

U disk inserted into the USB hub is not recognized, and then received other USB port still prompts: "With this computer connected to a USB device is not working properly ... "Data needs to be recovered.

Cause "A USB device connected to this computer is not functioning properly ... "There are a few reasons for the failure:

1, USB interface voltage is insufficient

2, U disk interface circuit loose or damaged

3, Crystal Vibration damage

4, the main control chip (drive chip) damage

If the interface voltage is not enough, you can change the environment and try again.

If it is a circuit failure, need to take apart for circuit inspection.

If the crystal damage, the replacement can be

If the main chip damage, you can replace the same or compatible with the main control chip to restore data, sometimes the same model of U disk, the main control chip is not necessarily the same. If you cannot find a matching master chip, you can decode the memory chip directly with pc3k false and other decoding tools, but you need tool support. If there is no tool to decode the memory chip, finally, the programmer can read the chip content after the manual reverse decoding, and then data recovery, complex degree is very high.

For the beginning of the case of the article, later learned that the same USB hub to take over the other U disk has been damaged, it is due to the USB hub failure, is likely due to current, voltage errors caused by the internal physical structure of U disk.

This kind of situation also counts as a warning effect, the best way to avoid data disaster is only backup!
