damaged flash disk How to Fix a USB Flash Drive USB Device Not Recognized In? USB Device Not Recognized arise because of two things as the cause. The first is due to hardware problems and because of software problems. For the second problem I have discussed before. This time will be discussed How to Fix a USB Flash Drive from the hardware side.
Many times we see flash storage disk is not recognized by the operating system due to the flash disk hardware itself. You can solve that problem by following these steps How to Fix a USB Flash Drive which is given below:
Step-1. Open carefully casing flash disk with a putty knife or a strong knife.
Step-2. take out circuit board flash disk from the slot.
Step-3 Physical examination flash disk for any damage or broken components by using a magnifying glass.
Step-4 Resolder back connector is normally plugged into the computer, then do a test connection with a PC or laptop, see whether the problem still exists. If the problem persists continue with these steps.
Step – 5 Resolder all the components around the connector and the controller chip. In particular, check the fuse type resistors. Sometimes changing the value of this resistor.
Step -6 Resolder Oscillator crystal (usually 12 MHz) and then reconnect the flash disk with a PC, see the results.
Note: – If you have the same crystal from a crystal oscillator, crystal oscillator 12MHz try changing from USB devices May you also take away from other devices such as USB memory card reader, USB drive or etc and make the connection as shown below.
1) Remove the crystal
2) Take the two wires and solder the wires at the foot of the crystal
3) Solder wires and crystals at the right place
Adjust the placement of crystals in a usb case and now the device is ready to be tested again.
I hope the step by step How to Fix a USB Flash Drive USB Device Not Recognized In the above will help you. But if all efforts fail to resolve your problem, the possibility of IC on the flash disk is damaged.
