So I bought an ssd and reinstalled windows on that drive. I wanted to format my old windows drive so I copied my most important files to an external hdd. I now have windows on my ssd and I tried to transfer my files form the external hdd but it's now showing. I did troubleshooting, I turned off energy saving on the USB ports, I updated the driver of the external hdd. In the device manager it recognises the drive, but I can't acces it. Is there any solution that I can do to get my files back?
