You connect it, but nothing happens, and you can’t access the files on it. How big of a problem this is will depend on how important the data on the drive is, but it will be an issue nevertheless. Another thing you will notice is that when you remove the drive, you might get a pop-up saying you will need to format the drive before you use it.

  3. Wait for CHKDSK to complete the scan, and give you the report. If there was any issue with the drive, CHKDSK will most likely fix it and tell you when it’s done.
