CIS preventing a successful defrag...?

[Guest]

[Dch48]

I'm having the same problem. Windows and Auslogics defrag will only get the OS drive down to 4/8% fragmented in normal or safe mode. This concerns me, as no software should be able to prevent the OS from functioning normally.

I'll give Smart Defrag and Defraggler a try.

I think you have other issues than CIS. On my system, both the XP defragger and Auslogics will finish the defrag and report 0% fragmentation. Auslogics will say that sfi.dat was skipped because it was locked and XP will say it was unable to be defragmented. Everything else on the drive is processed.

Windows Defragmenter ran fine here too, it completed the defragmentation task although it skipped sfi.dat (1.5 Mb)

It is likely sfi.dat is locked for use by CIS and thus Windows Defragmenter ought to skip it like it usually does for windows swap file (pagefile.sys).

AFAIK locked files, like pagefile.sys, are not usually defagmented although some defrag appplications may not explicitly report about them.

i use perfectdisk 10. sfi.dat is showing up in the boot files area. if another file bumps up against a locked file it continues on the other side thus leaving fragments. i dont know if sfi.dat belomgs to comodo or not. i uninstalled cis to see if i could solve the fragmentation problem. sfi.dat did not go away. if it belongs to comodo it is not deleted on uninstall. perhaps it is a windows file and cis just locks it. i searched the web for sfi.dat and could find nothing. would a comodo tech person please kick in here and provide any information?

Yes, Perfectdisk will do that,other defraggers don't. Auslogics looks for a space that will hold the entire file it is processing and will not have the problem of bumping up against something that is immovable. This will cause some empty spaces in the drive however. I tried Perfectdisk and I have to say it was the worst defrag program I have ever used. It tries to compact everything to the front of the disk and will churn away constantly moving and replacing things. I have games like Team fortress and World of Warcraft installed and in the process of "optimizing" my files Perfectdisk fragmented the large game files into at least 4 times as many fragments as they were before it started and would fragment files around the immovable ones. I'd rather have the empty spaces between things since due to the speed of today's drives,the need to optimize file placement and consolidate free space after a defrag is pretty much unnecessary.

PD takes way too long to defrag. PD will do both my drives in about an hour. With Smart Defrag about 10 minutes. Then I will use Page Defrag to do my boot files. Best thing......................both are FREE. Also no back round service needed.

my last post was not just about defragmentation. i want to know what sfi.dat is, what it does, etc. does it belong to comodo(cis). if so, when you uninstall cis why is the file not deleted? is this something the developers overlooked? to get back to defragmentation. to me all defragers are built in the mindset of say when windows xp was to about middle age. all defrag stratagies are obsolete given the size of drives today, the number of applications installed and the almost daily updates to many applications. file fragmentation is only one issue. for lack of a better name call it folder fragmentation. lets use the prime folder program files. each application has a folder under this. over time the files for an application get spread all over the disk. this causes just as much head seeking as file fragmentation. consider that a lot of people on a regular basis do a clean install of windows and then re-install all of their applications. their hard disk is then in the most possible perfect state. it would be nice to have a defrager/optimizer that could do this. all files that belong to any prime folder would be together. all files for a given application would be together. after that would come personal optimization which is a tale for another day.

It seems that nobody knows what sfi.dat is or where it came from- I don't think I had it until I got v3.9 though.

I use MyDefrag (new version of Jkdefrag)

http://www.mydefrag.com/

[Dch48]

I didn't like JkDefrag. I use Auslogics and every so often run the XP defrag afterwards to compact things more. CIS gives me no problems doing defrags.

I use MyDefrag (new version of Jkdefrag)

http://www.mydefrag.com/

I was wondering if Mydefrag and Jkdefrag would come up. I use Mydefrag because it seems to be faster than the defragmenter with Vista.

Might i ask why you didn't like Jkdefrag? Is there anything i should know about it maybe? Screwing up my harddrive maybe? Just curious.

I use JKdefgGUI, http://www.emro.nl/freeware/ which is a very nice front end, and provides easy access to some of the more powerful features of JKDefrag.

There is a new version of this for MYdefrag. Hopefully be released soon.

I found JK defrag to be no faster than the XP one. It also kept moving my large game files to the end of the drive and calling them "Space Hogs" which actually made the process take more time than the built in XP tool and seemed to make the games load slower. Auslogics is blazingly fast but presently offers no file placement optimization features. I like it however. If you want a fast defragger that has optimizers, you might try SmartDefrag from Iobit. (it didn't work right for me, but a lot of others swear by it and it's free)

I use JKDefrag and now upgraded to MyDefrag.
MyDefrag is more powerful than JKDefrag as you can now write scripts to customize optimization method.
For example, you can just defrag without file placement optimization or perform file placement optimization for a specific group of files only.  Dch48's problem can also be solved by excluding the game files from "Space Hogs" list.

[Dch48]

I have no idea how to write scripts and having to do that in any program is pretty bad design imo. JK /MyDefrag is way too slow for me, PerfectDisk should be renamed ImperfectDisk, and the optimization routines in SmartDefrag scatter my files all across my disk with huge gaps in between. I'll stick with the combination of Auslogics and the built in Windows tool.
