[First scan with Defraggler]

On those two programs I noticed the damage almost immediately after defrag. ChkDisk showed no disk damage, nor later when I finally decommissioned the drive.

As to the information about omitting SVI from defrag, I obtained that from a tech item online a few years back and I cannot remember the source, so you got me there.

 

I posted some months ago questioning the value of periodic defragging and asked if anyone could provide a link to a report of the results of a statistical analysis showing performance improvement from periodic defragging. No result. If such a paper exists I would love to read it! So right now to my mind the value of most defragging is theoretical - no proof.

Well, since I have 220GB free out of total 289GB it would be stupid of me to worry about defragging anyway. I do use the CCleaner weekly to get rid of excess.

 

As I say I analysed and did the Defraggler ONCE only without going back to defrag individual files. Surely that cannot have done harm?

Yes.

If you have a full 15% of your C drive in Sys Vol Info (Restore) files, plus a sizeable number of Temp Int files, and all the remaining files are defragged you will still have a high frag reading because Sys Vol Info and Temp Int files are not defraggable.

Further, if you have a large capacity drive with a lot of free space defragging should not improve performance.

My drive is now 54% fragged, which is normal. It fluctuates only a few points even without defragging.

To see a substantial drop in frag all you have to do is clean out all your temp files, and delete all your system restore points. It may then drop to around 15% frag, but you lose the safety of Restore Points, and as the points build so will your frag reading.

Frags on your HDD are like bugs at a family picnic. They'll begin reappearing a few minutes after a clean sweep.

 

Well thank you Kroozer. I would guess that therefore it is only worth Defraggling when your Drive C is 80+% full, which I would not allow anyway.

 

Incidentally I always clear Temp Int files before feragging - using CCleaner - which is how I came by Defraggler.

 

As I said I only Defraggled once and am unlikely to do it again. I just hope this one Defraggling can't have done any harm, can it?

Hello all

 

After running a weekly Windows defrag on my one year old VAIO latop running Windows Vista Home - I wondered whether the Windows defrag was actually doing anything.

 

The Defraggler analysis showed 55% fragmentation so I ran a defrag which reduced this to 45%, which as I said in a previous post, seemed rather pointless. If anything the system seems jerkier.

I always run CCleaner before defragging to make the job easier.

 

I cannot think that this 45% remianing consists of locked or immovavble system files - but since all I keep on Drive C is mainly programs perhaps this is so. Could it be so?

I actually think the Windows defragging tool is fairly good the problem is you cannot select individual files or folders to defrag.

Defragging in Windows is done by moving files from one location to another, for this to be success you will need contiguous free space to accommodate the files.

A file system running low on disk space isn't good, therefore clearing out the browser cache, temporary files and recycle bin would help.

Also some files / folders are locked by the Operating System and cannot be touched such as c:\pagefile.sys and "C:\System Volume Information\" (System Restore).

You can purge SVI by disabling and enabling the System Restore and using PageDefrag (but you much disable UAC to install it).

Thank you Richard S

 

Does that mean that you would recommend Defraggling indidvidual files from the 45% LEFT AFTER THE FIRST ATTEMPT? Or could it be that this 45% are all "locked" system files?

Hello

 

I use a Sony Vaio NS11 laptop, OS Vista home premium with 4GB RAM, and was not convinced that the Windows defragmenter was doing anything, having scheduled it for once weekly over the 14 months I have owned this PC.

 

Having been impressed by CCleaner, I thought I would anylyse the hard drive with Defraggler which showed 55% fragmentation, which confirmed my fear that Windows wasn'r doing its job. I ran the standard defragmentation which resulted in a measly reduction of frangemst to 45%.

 

This seemed poor.

 

I thought I would share my thoughts rather than try defragmenting again - which may be harmful to the system.

 

Regards
