Fix External Hard Drive Not Showing Up or Recognized: External hard drives are very useful when you want to increase storage space. They enable you to store data at a place other than your computer’s primary storage and that too at a relatively lower cost. They are easy to use. But, sometimes it may occur that even after connecting your external hard drive to your computer, it doesn’t show up or get recognized. There can be various reasons for your external hard drive not showing up like dead USB ports or driver issues. If your computer fails to detect your external hard drive, here’s what you need to do.
