How to recover data from a flash drive if the computer does not see it

If after a USB drive was inserted into a computer it is not detected, determine the cause of «invisibility» — in PC or flash drive.

For a computer characterized by such reasons of failure:

  • not working USB port often enough to relocate to another port and it will work. In the system blocks it is better to use the rear port. This is due to the failure of the port or lack of power. If there’s a shortage of food, you should leave enabled only the keyboard, mouse and USB flash drive, pulling out speakers and other devices and try again or use another computer to read.
  • not working driver – you need to install the appropriate drivers or delete the file INFCACHE. He is hidden and is located in the system folder in DriverStore;
  • not the right letter to media – after pressing Win + R, enter diskmgmt.msc and there to set your USB drive a letter which is not repeated in any of the media. To do this, select disk management, using the context menu is active the flash drive and there already it is assigned a new letter.

As can be seen from described, the return information after deletion from USB drive the lesson real. But expect a positive outcome is possible if the new data has not been recorded as a new layer on top of startingindex. And this will become clear after scanning the flash memory with special programs. Further, you can save the information in a new place and try to bring to the initial condition editor, if the file was only partially resuscitate.
