ABSOLUTELY STAY AWAY FROM NORTON

but I have posted about this topic before for finding how to truly defrag without only defragging the directory (Disk Warrior) and without copyin from one drive to another and back again.

I ended up buying TECHTOOL PRO 4 from what I heard on the posts that it generally seemed useful.

So far it works great for me. Can take a long time, but I've used it on multiple audio drives I use for pro tools for a couple months now with absolutely no problems
