Hi all, I have a 2TB Seagate external disk that I bought a year ago and use for my images. Is it advisable to defrag the external drive periodically like you would your C drive? I checked its status and it's 41% fragmented. I started to do a defrag, and after 2 hours it defragged one image so far. There's only 3 images and some files on the whole disk so it's practically empty. Should it take that long to defrag being it's 41% fragmented and is it necessary? Thanks for any advice.
