I know questions about defragging have been asked before but I'm having trouble finding an answer on this. I am wondering if defragging will help on my secondary/media drive. Its a 3tb drive that has been slowing down recently, scrolling thru files while watching a movie off it will cause the movie to jitter as I scan. The drive is about 3 years old and is 2/3 full but thats 1tb of free space. Again this is NOT my system drive, thats a ssd so I know it shouldn't be touched with defrag. Like always any suggestions would be appreciated.
