I was told by a friend that told me if I run Windows disk defrag too often it could be a bad for my hard drive. Is this correct or just bogus?

On my personal network, i defrag all the windows machines every 8hrs, it does it automatically. On the linux, and Mac machines i don't ever defrag of course. I read and write the to the drives constatly with downloads and backups, one serves as my VCR, the list goes on. During any given month, each one of my computers transfer about a Terabyte of just network traffic, let alone regualar use..Is the 8hr defrag to much? I was doing once a week defrag but it was taking a long time using Diskkeeper but with the 8hr defrag, the network is done in 30min, as opposed to 8 or more hours. Seems the time averages out...thoughts?

You've got me thinking now. I defrag every Saturday morning, takes about 30 Mins, should I be doing it less? The thing is, it does seem to help, and I'm not a 'hardened' user like some of the people are on this forum. I might try leaving it for a month, see how the PC responds, but then it might take ages to defrag, Hmmm, what to do?

Taking a long time wearing you out? I start the defrag just before going to bed. (I run SETI@Home 24/7) Wearing me out is just fine when I intend to sleep!

you may want to mess around with your hard drive partitioning instead, then you won't need to defragment, higher cluster sizes would also help.

IMHO the advice the original poster received is simply impressionistic. Defragging is not a bad thing considering that a badly fragmented hard drive causes the read/write heads to dance all over the drive in order to access a single file - because (duh) the file is fragmented!
Tip: you can defrag a drive much faster in cmd mode. Go to the command prompt and type defrag -a c: (for example). It will tell you whether you need to defrag. If you need to defrag, just type defrag c:.

I have seen a number of HD errors on systems that do not defrag at least periodically. IMO you should defrag before any new program installation, also if you have a newer drive I have seen less harm in fragmenting on a semi regular basis. It is true that if your drive is fragmented then you are causing a little extra work for the drive. Then again if nothing happens to change your HD's then you could be safe and only defrag 1 time a month, Also don't buy a cheap drive.;). Just my humble opinion though. Except that you really do need to defrag before and sometimes after software installs, or large file transfers. HD's are such low cost items that to be safe you can always set up a couple of drives in a RAID configuration. If one fails, get new one and you have a up to date back up as well.

I read Smart Computing magazine - monthly - you should check it out if you are a newbie - they had an extensive article pro and con on defrag - I do it weekly because I burn CD's - but they checked speed of drives - defragged and non-defragged - said there was no noticeable difference....and they basically did not recommend doing it much...

I have 10 partitions of various sizes totaling 200GB and have Norton System Doctor monitoring them 24/7, as soon as the fragmentation level reaches 50% on one of the partitions it lets me know and I defrag it. This means that some of the lesser used partitions, such as the backup partition, may not be defragged for several months. This seems to work well for me and my system always runs smoothly and quickly. Does anyone have any thoughts on the method I use?

if your back up partition consists of a single ghost file, then you dont need to defragment it at all, its hard to comment without knowing whats on your partitions! in general anything that uses lots of files to work is going to need defragmenting, i.e your windows partition, whereas a partition full of mp3's doesn't need defragmenting at all.

I have two hard drives in my PC. The one I use for backup I rarely defrag - I occasionally delete the files and do a new complete backup. I don't backup things that can be replaced from CD, but I do backup downloaded items and backup my email and bookmarks. I'm thinking now that three hard drives would be even better. One for the operating system and major or tried-and-true applications. One for Documents & trying out downloadable programs. And one for backing up the second one (also burn backups occasionally). Is there any advantage to having one humongous, partitioned disk, as opposed to several smaller disks? Seems like the separate disks would be easier and safer. hmmm, now I'm thinking a fourth to clone the bootable primary disk.

Partition the drive to minimize defrag time.

I partition mine, placing the "system" in one, the "applications" in a second and the "data" in two others (music, video, photos, etc). as a twist I have the page file in it;s own partition, first physical partition on the fastest drive, to keep it away from the other OS clutter.
Result is that it takes very little time to defrag the system partition, which is the most dynamic, aside from the page file. Anywhere from 10-30 minutes max about once a week seems fine. The files in the other partitions are fairly static and I just analyze them and defrag if needed after heavy activity.
I've read that defragging for performance is less important with the NTFS file system than FAT.
IMO I think the speed of the disk drive is the determining factor. A disk drive with a low seek time will suffer a smaller performance drop when heavily fragmented than an older "hamster cage" drive.

Hi
I don't know who had this idea, but when you use your pc, the hard drive might start out nice, but as you use any programme, it breaks into bits scattered all over the hard drive (fragmenting) basically when you defrag the machine, it puts all these bits back together again, and you'll see a big speed increase as well cos the pc is not having to look all over the place for data. Another reason to defrag regularly is that those small bits can easily get corrupted, defrag about once a week, and you should be ok, I've never heard of anyone having the drive wear out because of this!

I always run my defrag before installing any new programs, and I also run it on a weekly schedule, personally I've never heard of any "damage" to the HD itself by doing this, keep your HD clean and organized is always a good idea.
In short I wouldn't go crazy with it but a weekly run along with running it before anything new is installed has never given me any problem's.

I have been using computers for 13 years & I used to defrag at least twice a month. I don't believe you can do any damage to your hard drive but I will make 2 points. I have used Norton Utilities since it was a dos version. While defragging does put your files back together, I have never noticed any appreciable gain in speed; although it probably does speed it up where you can see it in tests, for the real world user you will not notice it. Therefore, the main reason people do it is moot.
A second and I believe a more important point is no matter which program you would use to defrag, they are all doing the same thing. They are moving your data to different places on your hard drive. Although this has not happened to me, there is a chance while moving your data, a file could be corrupted causing you to lose data or even a program not to work. This is enough reason for me to quit defragging on any regular basis. I now will only defrag twice a year & don't even know if I will do that.

I believe you might be at a greater risk of losing data by not defragmenting than by defragmenting.
I have hard drives that are in place since 1997 that are still going strong and we defragment them all the time.

If I were a newbie (that was two decades ago), I would worry about spyware, malware, and/or virues corrupting my system than being concerned about defragging my hdrive.
There are only two parts of the drive where 'wear-n-tear' are relevant: the head actuating unit and the bearings that carry the platters. These components are designed to operate for tens-of-thousands of hours between failures. The heads on ANY modern hdrive NEVER touch the media, execpt in the event of a crash, ie. a catastrophic physical failure.
Now, the head actuator and primary drive motor bearings involve hi-speed, permanent metal-to-metal contact, resulting in some amount of friction. Friction is the principal enemy of all things mechanical.
I've developed low-level OS and driver code in a previous incarnation and have NEVER seen anything in my hands-on experience nor read anything credible that would suggest that defragging is harmful or helpful to the hardware or the drive's contents. Defragging only makes the OS work more efficiently. However, drives are SO much faster than they were ten to fifteen years ago that defragging is less important to MOST (not all) users. Oh yes, drives are ENORMOUS as compared to drives from ten years ago. Consequently, there's a lot of contiguous space on most users' drives that never gets used.
This is not to say that a particular drive model or products from a particular drive mfr will live up to their warranties/specs. However, *IF* the drive lives up to its specs, then value of defragging really depends on HOW an indivdual uses his/her computer. So that as always, YMMV....

I've been defragging for 18 years and never had a problem. Unlike some, I have noticed an access speed increase if I had not defragged for a long time.
But I have now developed the habit of weekly backups, followed immediately by a Norton Speed Disk defrag. It works well for me. Whether related or not, I have even had misbehaving software begin working correctly after a defrag.
If you leave your computer on all the time (unless power saving is set to shut down your hard disk after after a period of no use), your hard drive and bearings are constantly spinning anyway. Without defragging he head actuation has to work harder to find all fragments of each file.

When I was learning to drive, my dad taught me to pump my brakes. Said it would reduce the wear on the brake pads.
Today I lease one car and own another. I guess if pumping saves me one brake pad every 100K miles, it is worth it.
The point is that there is another reason to pump your brakes, especially in incliment weather, to maintain control of the car.
Defraging a drive may not offer a noticable the performance increase for most of us regular users... It may increase the wear on a drive, but for laptop users, especially those that travel, defrag offeres an additional benefit of security.
When a file is deleted, often it is the pointer or reference to the file that is removed, not the file itself. If you delete a sensitive document, clear it out of the recycle bin, it could still be recovered by a savvy criminal.
By regularly defragging, you destroy the actual deleted file.

These days, with anti-lock brakes, you shouldn't pump them at all. It messes up the computer control. But if you set your parking brake each time you park, you'll align the brake pads properly and they will wear evenly giving you the longer life you are trying to get.

I defrag primarily for boot speed. To that end I use BootVis on one puter and System Mechanic on another to Defrag the Registry every time I add a program or change my start programs. Then I defrag the whole drive for optimization. That puts me in the "several times a week category".

Well, apparently I am one anal defragging, etc. maniac. I only have my own home computer use primarily for Internet and gaming. 240 gigs of storage. Personally, I have a mantra I complete multiple times daily that makes me feel better, and I feel improves my performance overall. I run Windows XP Pro Disk Cleanup on both drives, then SafeClean Utilities, then Norton Systemworks 2K4 one-button checkup, then RegScrubXP, then use Diskeeper on both drives. Also, at least once a day I also use Diskeeper to run a boot-time defrag. Overall, one drive is 5+yrs old and the other is about 4 months old and (knock on wood) I've never had any problems and seems to run like a champ to me.

Defrag organizes files. If your drive has less chatter time looking, then you would think it would be more productive with a shorter seek time and therefore less wear.

That's a valid theory, based on the activity the defrag causes on the drive. What your friend forgot to take into account is all the extra searching and scanning a fragmented drive has to do, which also creates wear.
It's similar to the exercise debate. Assume your heart is good for a specific number of beats. If exercising increases your heartrate during the exercise, doesn't it shorten your life?
The answer is "No". The exercise helps your heart run more efficiently, and slowly, between exercises, so that it beats fewer times per day, allowing for a longer life.
The same is true for your hard drive.

Defragging does not wear out your hard drive - in fact it EXTENDS the life of your drive and your computer for 2-3 years on the average. Using Diskeeper's "Set It and Forget It" features lets me go about my business and never have to worry about defrag. It automatically determines how frequently defrag is needed and runs in the background. What more could you ask for! Plus it handles extremely large drives. I've read lots of places that lack of defrag causes crashes and reliability issues. This is even posted in Microsoft's knowledge base.

I would have first asked my friend just what constituted "too much". Some people do it after each program install. Others do it at some specified interval. Still others (like myself) do it when we notice a decrease in performance. Since most drives have a MTBF (Mean Time Between Failure) cycle in the hundreds of thousands of hours, and there are software programs that are designed to defrag on the fly like Diskeeper, It ain't likely so to speak.

Let's get real. A hard drive is warranteed for 3-5 years (as stated above). How many of us will not upgrade our systems/hard drives in that time frame? You can't wear it out in just 3 to 5 years if you defrag every day.

To defrag just to say you did is a waste of time, resources and unnecessary exposure to problems (ie: why open your cars valve cover if you don't have reason to seriously suspect a problem there?).
I clean up trash (ie: delete cookies, .tmp files, cache files, recycle bin, etc) periodically depending on computer use (ie: have my kids been all over the web?) or in anticipation of an install (ie: major MS software patch).
Once that is done, I then defrag each partition ... twice. It seems the first defrag leaves behind some fragments probably just because there was not enough 'contiguous' (sp?) space for a big file. Running it a second time seems to clean these left overs up.
I have used Norton and other utilities, but I found no real difference in results and the defrag process itself took longer.
To me the longer something takes, the greater something bad will happen (ie: powerfailure) ... Murphys Law!!!

Let me first preface my comment by stating that I am a Product Manager/Engineer for a major disk defragmentation vendor.
Simply put, defragmenting does not wear out a hard drive. Here's a simplified example: accessing a file in 1000 pieces once a day for a calendar year totals 365,000 disk I/O's! Compare that to a one time defrag (1000 disk I/O's one time) and then 365 more (1 for each day the rest of the year) for a total of 1365. An exponential difference.
Borrowing from another comment in this thread; disk life is measured by MTBF (mean time between failure) which is basically a measure of disk activity. The less activity wasted on file fragmentation, the longer your drive will be around to do useful things.
As for safety of defrag, that is left to the operating system to manage, not the defragmenter. It is designed to ensure defrag is 100% safe.

OK ... this is the definitive statement on defragging. Simply put, NOT defragging is much worse for the wear and tear of your hard drives than defragging.
Defragging also often includes some basic checks on your data's integrity, just in case sectors on the disk have failed or are about to fail.
And once a file has been defragmented, it usually will never have to be defragmented again. That means the next time you defrag your hard drive, it will only be checked for integrity, and will not be moved.
As long as your computer is on, the disk will be spinning, so the only way to minimize spin-related wear is to turn the computer off, which is not an option for many computers. A very fragmented drive not only causes disk I/O to be slow, it is also a very inefficient for the disk read/write heads, causing much more wear and tear.
So, bottom line ... you can be slow AND stupid, or you can defrag regularly.

) Mind you, I'm not suggesting that defragging is unnecessary, just not as important as some know-it-alls suggest.
