I’ll try to make this as quick and painless as possible, hopefully it doesn’t take 27 hours like it did with me last time.

  1. Find your drive letter – head to “Computer” on your laptop and look for the one that corresponds to your portable drive. This won’t be C:/ as that’s your PC itself. It’ll more than likely be D, E or F.
  2. Open your start menu and type “CMD” , right click on the little black square and click Open As Administrator. If asked to allow security, click yes.
  3. You should have a black window with a blinking cursor like this one here.

Type this command when you get here.

chkdsk D: /f /r

If your drive is different to D, change it to match. Once typed, press enter. It may ask if you want to force eject the drive from any running applications. Say yes (usually the Y key) and let it continue.

With any luck, that should bring it back to life again!
