Welcome to the forums, newcomer!
You might want to give us some meat to the potatoes, please include the make and model of your drive as well as it's age. Also, can you check and see what OS version you're on assuming you're on Windows 10? If resource monitor shows that your disk is at 100% usage in spite of the system being idle, then what you have is known as a memory leak which is found on Windows 8 and above and can happen due to a corruption of the OS.
