I am going to clone my HDD with Windows XP on it to a replacement SSD. How important is a defrag in this process? Should I do it before? Or after?
Also – do I need to back up my main boot drive before I defragment it using Windows XP? What are the chances an accidental ‘shut off’ (e.g. power outage from a thunderstorm, electrical glitch) will cause the drive to become corrupt if it occurs during the defragmentation process?
Finally – about how long should it take Windows XP to defragment a boot drive having 150 Gb of programs/data ?
