Re: What is best version of FTM to manage large data
scandisc and disc defragmenter are two of the most important maintenance utilities you can use on your computer.
The reason they "re-start" is because you do not let them 'run", every time you do something with the computer they will re-start.
I have a 120Gb hard disc and this will defrag in less than an hour, why? becaue I run defrag every week (sometimes more often)so it does not have so much to do. I also add and remove a lot of programs in a week so I need to defrag often.
I would suggest you start defrag and then go to bed, by the morning it should be all done (because you have not been using the machine for anything else).
Leaving the machine on overnight like this will not harm anything and when you defrag the following week it will be even quicker.
Just go for it, I am sure you will notice the difference
All the best
