Whether you have a USB flash drive or an external hard drive, you might come across an error that prevents you from accessing your files on your drive.

2. Go to the Security tab, hit Advanced, then click the Edit button.

3. On the Owner tab, modify the ownership of the specified account.

Solution 2 - General Solution - Check USB port

Before trying other technical solutions, check first if the USB port on your computer is working or not. Insert your USB drive to another port of your PC. If it works, the problem is with the port. If this still doesn't work, connect your USB drive to another computer's USB port. This will check if the problem is with your USB drive or your computer itself. If the drive doesn't show up in the Disk Management, you might need to replace your USB drive.

If your USB drive, ports, and computer are all working, you might want to perform technical fixes.
