Sometimes a drive doesn't run the way it's supposed to. For example, what do you do when there are essential documents on the drive and you can't access them? In many cases, you should have a backup of those files and be fine, but sometimes, disaster strikes when you least expect it. You might be found with a drive and no backup or with newer files that didn't get backed up yet that are critical. When you find yourself in this situation, enlisting a professional to attempt a data recovery using advanced tools is the best action.
