Is Your External Hard Disk Drive Slower Than Before?

Could your PC have a virus? Is there a setting in Windows 10 that is slowing things down? Or could the problem be something as simple as changing cables? Plugged your external hard disk drive into your computer and noticed it's slower than it used to be? If you use the drive regularly, this could be easily explained: perhaps it's slowing down because it's old or needs defragging.īut if the drive is only occasionally used, and you've just spotted the speed issue, there's a chance it might be related to something else.
