| | 30% Defragmention Hi, I've got a new PC with Vista Home Premium installed.I have 30% of defragmented files on my C Drive.I have tried a couple of different Defrag utilities on it O&O,Perfect Disk etc and after a Defrag run the 30% of defragmented files are still there.Also tried offline Defrag runs with the same result.When I was using XP Pro with the same programs the defragmentation level was usually between 3 to 7%. I believe Microsoft state that NTFS formatted disks don't need Defragging. Thank you |

| | Re: 30% Defragmention Vista has its own built-in defragger which runs invisibly in the background. It is actually scheduled once per week, but it runs at the lowest CPU priority and the lowest I/O priority, so it may well take hours or days to run. The important thing to remember is that it works just fine. You don't need to pay it any attention. It has no impact on your day-to-day usage (because it backs right off as soon as you do anything). Finally, "30% fragmented" is almost meaningless. The only thing that matters is what impact this has on your real world performance, and there is no easy way to translate 30% into a responsiveness figure. Note that the Vista defragger does NOT concentrate on minimising fragmentation or making the disk "pretty" - it is targeted at optimising the disk performance. Quite a different thing. Therefore you could and should forget all about disk fragmentation. Don't use any other defraggers (some of them actually mess up the file optimisation that Vista performs). Just get on and use your PC for its real purpose, and be thankful that you have one less thing to worry about. SteveT |

After a bit more research I got this below. With Windows Vista it is not possible for any defragmentation software to defragment the files from System Restore (C:\System Volume Information), because there is a bug in "volsnap.sys" (a component from Windows). Until the problem is solved we cannot touch this files for safety reasons and have to exclude them.
