I was told by a computer repairman that it's not necessary
to defrag my laptop. If the hard drive gets full, remove
files and always make sure I'm using a virus protection.
What are your thoughts?
You don't "have" to defrag a disk. There are some benefits to it but nothing
very serious will happen to you in general. It's possible, not likely but
depending on what you use it for, for it to slow down your computer.
OTOH I do defrags about monthly on most of my drives and when I'm using it,
after every session of video editing/rendering. If I don't my computer will
come to a screeching near-halt due to the huge, fragmented files on that one
very large drive should I continue to work in video.
If I wait over two or three sessions to do the defrag, then in this case
there is so much work to do that it takes hours to do a defrag. But by doing
it after every session it only takes around 20 minutes so I just go on and
do something else while it's running or let it run overnight if I'm done for
the day. Point is, the worse the fragmentation and the larger the drive, the
longer it takes to defrag. Especially if the drive is allowed to get full to
the point of only about 15% free space. If free space gets low enough,
defrag will cease to be able to work.
IMO it's best to defrag periodically. Find a schedule that works for you
and doesn't take several hours to run. Start with monthly and the, two, then
three, or 3 weeks, whichever way it takes you. Everyone's needs are
different.
But it is not specifically necessary to run defrag.
