The USB hard drive not formatted error is very annoying, especially when you want to access important data from your drive and do not have it in a back up drive elsewhere. Fortunately, there are ways to fix the problem. Before we look at the solutions to the problem, let’s talk about why this error message pops up. Here’s the explanation: the disk you’re trying to access either has not been prepared for use by your Windows operating system, its file system has been corrupted by malware or because of a improper system shutdown, or it has been physically damaged from inside. A hard disk can be physically damaged due to various reasons, such as a water spill, extreme weather conditions, bumps, knocks, etc.
The drive not formatted error can also pop up when the drive is not properly connected to the computer, or the USB connector or the USB port on your computer has become faulty.
