Windows 7: disk defragmentation and DisKeeper

disk defragmentation and DisKeeper

I was unaware that the disk defragrmenter in Win 7 is really a trimmed-down version of the defragmenter from DisKeeper.

I found this Microsoft Knowledge Base article interesting:
Third-party disk defragmenter tools for Windows

Is that good or bad in your view? Any chance you will use it or will you stay with Auslogics?

After eight months I'm still at 0% fragmented according to Win 7. Not sure if that is because (as I understand it) the defragmenter constantly works in the background in addition to it's scheduled runs.

I'm subscribed to this thread I would also like to know what the answer is.


I too have 0% fragmentation after 9 months. Hard to believe unless the defrag utility is occasionally working in the background in addition to scheduled defrags ....


ANYONE KNOW THE NITTY GRITTY ON THIS?

Win 7 will disable defragmentation for a solid state drive (SSD).

I do not use the Auslogics defragmenter.

I do use the Auslogics Registry Cleaner (and my system has not crashed and burned).

My defragmenter of choice is Contig.exe from the SysInternal's people.
Contig

To use contig:

Go to an elevated command prompt.
Go to the folder containing Contig.exe.

To learn about the contig command options, type
CONTIG /?


To defragment the D drive, type:
contig /s /v D:\*.*

after running contig and seeing what happens,
then next time you may want to use:
contig /s /q D:\*.*

This will be faster since you have now chosen "quiet" mode as opposed to "verbose" mode.

To only "analyze", but not actually defrag, then:
contig /s /v /a d:\*.*

You also run contig twice, right behind each other to get a couple more files defragged (if contig indicated that some were still not defragged).

Personally on machines using normal HDD's (not SSD's), I prefer to use Defraggler from Piriform. You can find it at Defraggler - Download

Take a good look at that page and look below where it says "Huge thanks to those of you who have already contributed and support our software! You can still donate here."

You'll see 2 links, one from Filehippo, the other from Piriform. You can download it for free at any of those 2 links.

What makes Defraggler different is that other than offering you a Quick and Normal Defrag option, it also allows you the option to allow it to move larger files (which you can determine in the options) to the outside of the hard drive. When a hard drive rotates, the outer edges of each platter spins faster than the inner sections of the disc, so it makes sense to keep the bigger files to the outside so that loads faster.

I think that KB article is dated, It is certainly true that XP, Windows NT and 2000 defraggers were based on Diskeeper, but I don't think Windows 7 is. I believe Windows 7 is all Microsoft.

I believe deffragler is not VSS aware, which can play havoc on your shadow storage.

You will find the link that I gave in the original post informative.

Although I use Contig, Defraggler is safe to use.

Using defraggler will eat up your system restore point shadow space. It is not VSS aware and the OS will interpret the movement of disk blocks by defraggler as modifying the associated files and will replicate the blocks, eating up the allocated restore space with the end result of loosing restore points. If you don't care about restore points this is not an issue. If you do it is.

The Windows 7 defragmenter is superior and optimizes defragmentation to minimally affect volume shadow copies and optimizing MFT fragmentation etc. Why would you use some third party defragmenter like defraggler rather than the Windows defragmentwer?

And the original link you posted is not relavant to Windows 7 AFAIK.

Correct. The defragmenter that came built-in with Windows 2000, Windows XP, and Windows Server 2003 is a pared-down version of Diskeeper.

If the information is NOT correct, then someone needs to talk to Microsoft.

Please read the article referenced by the link.

Please note the last revision date.
