Signs overview

Here are the most frequent signs of trouble. A USB drive becomes unreadable when you see the following:

Use Partition Recovery to open unreadable flash drive

  • The flash drive is connected to the computer, but you get the message “Insert disk”.
  • When you connect a USB flash drive to your computer, it starts to hang out.
  • When a USB flash drive is connected, the USB flash drive is not visible in Windows Explorer.
  • You receive a message stating that you need to format the disk, since it is not formatted or that a data error has occurred.
  • Your computer detects the USB flash drive in the system, but the BIOS does not see the bootable USB flash drive.

In all these cases, you will not be able to access data from the flash drive.

Action 1. Check the flash drive

Try the following methods to check if the flash drive is OK:

  • Try inserting the USB flash drive into another USB port.
  • Doesn’t work? Connect it to another computer. It may be that the flash drive is simply incompatible with a specific computer.
  • Another way to check the USB flash drive is to see if the computer can see the connected USB flash drive in Disk Management. To do this, press the hotkey combination Win + R and type the command “diskmgmt.msc”. Press Enter. Now check whether the flash drive is found in the listed volumes. If it is so, click on it. In the same window, you will see the description of the flash disk. If you see a Healthy sign, just right-click and select Open. If the flash card is not found in the listed volumes, try to insert and remove the flash drive one more time.
