So I did a directory graph for my HDD , and this is what I got as you see in the image with DiskWarrior. It seems pretty damaged according to the graph. I just want to know is DiskWarrior worth the price? it costs a $100 just to rebuild the directories of your HD. Does it really help? Or do they exaggerate it? My computers runs fine, no errors and no crashes and after 4 years of use, I see its pretty snappy just as the day I got it. Do you guys recommend to use this software?
