After playing a DVD back-up I made that skipped quite a bit, I’ve begun sifting through my back-ups to see which work and which don’t.  Part way through, my free space was going down and discovered my drive hit 16% fragmented.  This is the highest I’ve ever had a drive and like a moth to the flame, I’m now trying to see if I can break 90% by continuously copying, decompressing, recompressing and deleting ISO files of drives.  Let us see who gives in first, man or machine.  BRA HA HA HA.
