"When is the best time to schedule drive defragment........?

......is it (A). just when your screensaver turns itself on?
or is it (B). sometime after your screensaver turned on?


Consider the following, to avoid need in scheduling one
might choose the best optium time, but when you come
back and move your mouse which is the optum time to
make it cacnel at the same time to minimise overloading.








Answer: Never schedule it or it will slowly crash globally.
If there was a optium timing to a human user then it would
be a digital clock and if there was a digital clock to solve
the defreagmentation issue of the drive, it would not need.
