Defragmentation

[AliV]

When i run disk defragmentor i get a bunch of files that dont want to defragment, how do i fix this?

Thanx!

Some files are too large to defrag (ie. 3GB files), while some are system files that Windows has placed in a specific area for some reason or another. If the defragmentor says its done defragmenting, then its pretty much as good as it can get.

Perhaps you could try 3rd party defragmentors, but I'm not sure which ones are good/bad.

If you're using Windows I'd suggest trying Diskeeper 9. It's out there on p2p you just have to look for it. I run that about once a week (and more often if I've been downloading really large files) and it seems to do a better job than the default Windows Defrag. I highly recommend it. One of the neater things about it, is that it can do a "Boot-time Defrag" meaning it can defrag those pesky system files that aren't defraggable when Windows is running.

Try it out and let me know. Also, sometimes you have to run it through several times to get the full effect.

:p

Download it and run it, it will shut down windows and restart it, Before anything loads into windows it will defrag your hard drive so it should move anything but bad sectors and it will then shut the computer down again when it's finished.

this means that you can run the program at the end of your day and go to bed.

Superb and easy to use :)
Hope it helps

It is saying at the end of the defrag that the following files could not be defragmented. They are not 3gb and they are not system files

Can you copy and paste a log of these? Or at least give us some file names. Then we can have an idea of the type of files you're talking about.

As previously explained, some files cannot be defragmented as they are constantly in use by Windows, or have a fixed location on the drive for specific reasons. It's a bit like changing the tyres on your car whilst driving - not recommended for safety reasons.

Post a list of the files you are concerned about and maybe we can check whether they legitimately should have the don't move attributes.

But Diskeeper can move system files...

It can even defrag the paging file and the MFT.

I use nothing but Diskeeper and have yet to have a problems defragging a file.

I guess it's hard to get people to switch from Windows default software :mymymy:

I was under the impression that the win2k/xp defrag tool was based on diskeeper, with most of the options preset...

perhaps im wrong?

They are films not system files...

[AliV]

I ran that defrag program, it ran for about 3 seconds and then finsihed, it didnt do much at all.

[iissmart]

They are films not system files... Give us some of the file sizes too, just to see how big they are. And perhaps the extensions, like .mpg, .avi, .mov, .divx, etc..

Yes you are correct. But it's based on the old Diskeeper 4.3 lite I think. The program has progressed much since then. The win2k.xp defrag tool doesn't have the boot-time defrag, however.

How many fragments there are on those files? I wouldn't bother forcing to defragment large files (say 700 MB) if there are only little (a dozen or two) of fragments on them. If the disk needs to make few extra diskhead movements while reading the file, it doesn't decrease your performance so much you'd notice it. When the average fragment size is getting low, below 10 MB or so, then it starts really affect on the read performance.

perhaps im wrong?More like most of the options absent. Diskeeper 9 Home edition, like windows defrag, can only defrag one disk at a time. Pro can defrag multiple disks, but isn't smart enough to know when two partitions share the same physical disk. Boot time defrag is a Diskeeper Pro feature.

They added a few neat options in addition to their smart defrag, which back off from work when other disk activity is in progress.

Very large files won't get defragmented unless you have like 2xfilesize free space. You could try the background scheduler with the optimize free space in an attempt to get the contiguous free space required to defragment the large files. Also note that some of the options, like 'quick', won't even consider consolidation for large files which have 'few' fragments.

The diskkeeper online help explains each of the methods and what can be expected.

The video files I worked with were from 20 to 120GB on 80GB and 160GB disks. The best I could do to avoid fragmentation was to create the file with a program so it would use one file allocation unit, but this didn't always work as some of the video capture/edit programs I used would delete the file before writing.
