Solved when I defrag my Win 7 HDD why are there a lot of gaps

Hewlett-packard / Presario cq62 notebook pc
May 12, 2014 at 17:31:06
Specs: Windows 7, 4.0 GB Ram/AMD 2.2GHz
I recently replaced my hard drive, as my old one was dying. I was downloading a lot of programs, and it became fragmented, so I was using my defragger.

After I defragged, it seems there are WAY more gaps left over than on my old hard drive. And, I have filled the disk space to approximately the amount as on my old hard drive.

Any thoughts or ideas? Thank you.

P.S. I also am using my son's PC, as my Compaq Presario died on me.

Often has been suggested to defrag in safe-mode. Another is to disable the page-file (swap) file prior to defrag; and of course re-enable it afterwards. (Page-file is the large "unmovable" file you usually find marked as such on the graphic display showing state of drive - before and after...)

Also I have found that unless one is using a third party defrag utility there will be gaps left by the bundled windows one; it will only tidy up as it were and leave gaps. I have found those gaps to diminish a little more by repeating the defrag a few times with the windows util.

I have tried several other defrags in the past (mostly with NT, W2K, XP) and found not a lot to choose between them... Finally stayed with the "basic" M$ one...

Defragging doesn't necessarily bunch all the files together. Defragging pulls together parts of files that have been placed in different areas of the drive to make them continuous. The gaps may be due to files that windows can't move either because they're system files or files related to software in use.

Sometimes you get better results by defragging in safe mode thus reducing the number of files in use.

Hi, there, DAVEINCAPS,

Thank you for your response. I suppose, then that those gaps are due to the unmovable files that I know are there on the drive. And, I guess I have less files than before in comparison to those unmovable files.
Although I do have a lot of games on my drive which don't have to be installed.

Anyways, that sounds feasible.

Appreciate your help. Take care & God Bless!!!

Unlike Windows 95 defragmenter, the more intelligent ones like in Windows 7 appear to leave space for filling in programs and system updates during future defrags so everything does not need to be moved during every defrag.
From my observations only, not from any official source.

You have to be a little bit crazy to keep you from going insane.

Hi, Fingers,

Thank you for your response. But, I do not use the Windows defragmenter. I use a program called My Defrag, which optimizes the drive as well as defrags it. I suppose other programs do do that, also, but I've found that it is a great little tool.

You take care & God Bless!!!

Modern de-fragmenters leave space between files to allow for further expansion. In the early day all files were bunched together at the beginning of the disk, the effect of this was that as soon as any file started expanding, it got deragmented. The modern method allows for a bit of slack.

Unmovable files are shown up as such and a modern defragmenter will try and keep files that away them.

I wouldn't get to hung up on defragmentation though. A file system like NTFS is more resilient to fragmentation and when it does occur, because of the efficiency and speed of modern drives, the performance drop is minimal. The cost in added wear and tear may well out weigh the benefits - and of course, never defragment an SSD drive for that very reason.

Defragmentation is generally fragmenting the data so as to create a continuous space ie. the data will be in a series. You can check for the boxes or the colors below as what the different data categories imply.

With My Defrag, there is an option to "Consolidate free space" in the script menu as shown here: http://www.mydefrag.com/img/Snapsho...

If you select that script, all the data will be moved to the beginning of the disk so that the free space will be joined together in one contiguous block as much as is possible.

I used to use "My Defrag" on XP. One of the features I liked is that it left gaps at the front of the drive so that new programs could use that space rather then being shoved to the end. I also liked the idea that space hogs, such as big videos, forth were moved away from the beginning of the drive. I only every used their "daily" defrag because the weekly and monthly options went on for hours. Felt they were a bit hard on the HD for little benefit.

Wow, thank you so much, StuartS, buggsbunny(say, do you post on Downturk, BTW? If so, I've seen ya!), phil22, trvlr & Derek for your lovely responses. I appreciate all your input.

But, in answer to trvlr, as you can see by my earlier post, I do use a 3rd party defragmenter. And, I have noticed(after QUITE not finishing my 4th defrag after formatting my new hard drive), that there are considerably less gaps than in the previous 3.
So, I think what you said makes a lot of sense.

phil22, I believe I have used that once, is it good for helping the disk? Thanks!

And, Derek, I don't know why you don't use MyDefrag anymore(of course that's your prerogative but I do like that fact that it optimizes your HD), but I have never used Sytstem Weekly or Monthyly, either, as I do it more on an almost daily basis. I KNOW, guys, that defragging too much can grind on the same areas(not good), so I try to do it as little as I can. Usually I determine that by using the Disk Doctor in my Advanced System Care, OR if I analyze, and find more that 1000 fragments(especially!!!), then I do it.
I will have to slow down on my defragmenting, but I hope that perhaps a couple more sessions & the gaps will subside.

Again, thank you so much, for ALL your input. I appeciate it!!! Take care & God Bless!!!

Re your #10

The reason I don't bother with 3rd party defrag programs any more is because I'm now on a modern Win 8.1 computer with a fast hard drive. The benefits are therefore minimal so I consider the Windows defrag to be adequate enough. However I do consider "My Defrag" to be a good package for those who wish/need to use it.

So, Win8.1 is a faster system, or you just have a fast HD? Just curious, 'cuz I don't think too much of win8. I much prefer 7, as, well, one person was saying(and I know, that's only one), that Win8 is comparable to one of Microsoft's mistakes...I think it was Win98, but not sure. Anyways, bottom line is, they could have spent more time fine tuning it.

And, although Win7 can be a slower OS, I think it's great. Just MHO.

Vista was (still is???) considered by many to have been a mystake... But there are also more than a few who actually got to like it...

'95/98 I found OK; '98SE especially - once the bugs were ironed out in '98 which meant it became '98SE.

Re #12. Short answer is "both". Windows 8.1 is the fastest system I have ever had and I also have a fast HD. Not an SSD though, which should not be defragmented. It is with older computers that defrag is more important - HD's and hardware generally have come on leaps and bounds over recent years. For example, Defrag was almost essential in the Windows 95 days when hardware was much slower.

Opinions abound about Win 8 but I find it fine. It's just another computer so you can do everything you were able to do with previous operating systems plus a bit more. The main sulk is lack of the previous style start menu but I don't really miss it - as always with Windows there are lots of different ways forward.

Vista was the one regarded as a mistake (Win 98SE was fine for its time). Vista was bloated and slow, so you either had to fix it or wait for the hardware to catch up with it. With faster hardware it was not so bad. Win 8 is not a "bad system" just that folk didn't like the interface - which is due to be changed this year. Many gripes about Win 8 seem to come from those who have never actually tried it.
