Defragmentation Programs for NTFS...

Do any of them actually work?? I have tried diskkeeper and oo-defrag and they seem to do the same thing. A full pass only defragments a small percentage of the whole. After running complete on oo-defrag 4 I have almost 15,000 fragmented files. I have 10GB of freespace so I see no reason why it can not be fully defragmented... If I run it again the number will go down. Why can't you set an option to run till there are 1% fragmented files or something... John

Do you get an error about contiguous free space being < 15%? I use the defrag in XP Pro, and it works ok. It consolidates the files. I wish it would consolidate free space though. I tried that oo-defrag, and it just thrashed for hours and did nothing. Norton Systemworks 2003 works excellent at consolidating and sorting everything, including system files.

I've got the same problem on W2K. I've defragmented a HD 5 or 6 consecutive times and the disk isn't defragmented yet! I suppose the defragmentation needs no interruption and other processes stop it. If you find a solution, I would be glad to hear it!

Don't worry about it: I always have been quite skeptic about defragmentation results. People often defrag their disks but do not measure results. Defragmentation under multitasking/multi-user environments can be frivolous: several programs will ask for disk sectors on distant points of the disk at the same time, so, with some luck, a "carefully fragmented" disk can even beat a defragmented disk. WinXP (IIRC, but maybe it was Win2k) have even introduced out-of-order prefetch when loading programs, so defragmentation will help nothing. Get one of these fragmented files and make a simple proggie to read it. Run it several times and measure the result. Then, defrag your disk. Run your proggie several times again and measure the result. You can do it on anything you choose - from .bat to .net - A customer

Does Windows XP has this feature of auto-defrag if the machine is left idle for some period of time(15 mts or so),i'm not sure if it does defrag but i think it monitors programs for the dlls they load and then rearrange them in some contiguos order. Regards, Kannan

Try PerfectDisk[^]. It is by far the best defrag utilitiy I've used.
Thanks for the tip... John
