Is defraging necessary?

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?

Occasional defragging is beneficial, e.g. once every two or three months,
depending on the level activity. You won't notice any substantial
improvement in performace unless your partitions are very heavily
fragmented.

You should make sure that the amount of free space on each partition is
around 20% of capacity or more. Defragging does *not* free up disk space.

Yes, you must install virus protection. I have used Microsoft Security
Essentials (http://www.microsoft.com/Security_Essentials/) since December
last year and have had no problem. It's free.

The WinXP DEFRAG app first evaluates fragmentation on
a drive, then advises whether defragmentation is needed or
not. Ordinary WinXP users can rely on this advice.

*What* computer repairman? What company is he with? If, for example,
he's with the Geek Squad, or any similar big-box store, he probably
knows next to nothing and his opinions are worthless. I strongly
recommend that you stay far away from such companies.


that it's not necessary to defrag my laptop.


It's normally very seldom necessary. You can do it, but you don't have
to do it often.



If the hard drive gets full, remove files


That's a statement that's next to meaningless. Yes, if your hard drive
gets full (or anywhere near full), you have a problem. But simply
telling you to remove files without any guidance on what to remove is
no real help at all.

Moreover, if your hard drive gets near full, removing files is at best
a stopgap measure. The problem will return quickly. The only real
solution to the problem is to buy a bigger drive.


and always make sure I'm using a virus protection.



He got that one right for sure. However, anti-virus programs are far
from equal, and which one you choose is very important. Unfortunately
the two biggest sellers, Norton and McAfee, are also the two worst
products.

I recommend eSET NOD32, if you are willing to pay for an anti-virus,
and either Avira or Avast, if you want a freeware product.

And one more point. Run an anti-virus program, and *also* at least two
anti-spyware programs. I recommend MalwareBytes Anti-Malware and
SuperAntiSpyware.

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.

I can envision a situation in a data center with hundreds of thousands of
transactions per minute where defragging may be of some slight benefit
(assuming an NTFS file system).

I can also imagine a user devoted to daily defragging experiencing a power
interruption during a critical directory manipulation process.

On a small computer with many add/delete/grow/shrink operations, defrag
can significantly impact file access times and can be very noticeable to
users if their system was badly file fragmented before the defrag.

White-Space fragmention is not normally an issue, but a file that is
fragmented into 8000 parts will have an impact on system performance.

This argument has gone on for decades, but it's the people that maintain
systems across many areas that know the benefits of defrag.

in my opinion, if the amount
of data has not exceeded
50% of the disk, then you
may be wasting your time
in defragging.


And that's why people don't really pay attention to what you post here
DB.

It's not about how much free space you have left on the disk, since free
space has little to do with fragmentation, other than making it worse
when you have less free space.

What does impact fragmentation is the number of ADD/DELETE/SIZE Changes
you make to the files on the drive.

I've seen a single PDF, on a drive with 800GB free space, fragmented
into 29,000 parts. It would take up to a minute to load, after the
defrag it took a few seconds...

I'm curious. How did you know the file is fragmented into x parts? What
software did you use to see this fragmentation?

Have you ever used Windows Defrag or JK-Defrag or MyDefrag?

Windows Defrag will generate a report after you Analyze the disk, it
shows FRAGMENTS, File Size, File Name (includes location).

"Him" bum? Why you keep referring to your mum in such derogatory terms is
beyond me.

There is plenty of evidence that file defrag improves drive system
performance, only a person with limited experience would suggest
otherwise.

What about defragmentation with a RAID system? Doesn't this system eliminate
file defragmentation? I am under the impression that it is two copies of
everything (one on each drive), it is a faster (and ??more stable system??)
and more reliable system?

Those new HDD's that are flash drives, SSD I think, they don't need
defragmentation I saw in some tutorials. Since they are flash based, if I
defragment my flash memory cards or my memory sticks, is this a bad idea?

Thank you.
