Defragging HDD

My brother has an HP Pavilion a6745f. Since it is an HP, it came with an extra partition on the harddrive with all of the windows install files instead of boot disks. Well for some reason HP set it to boot up from the bios in raid mode and there is only one hard drive. I did the regedit trick and switched it to AHCI mode, but windows still recognizes the drive as a 0+1 raid array. Is there a way to fix this without losing all the data on the drive?

My main question though, is that this particular "array" (single drive) is like 40% fragmented and I have tried smart defrag, defraggler, system mechanic and windows' built-in defrag program. None of them seem to help at all. I ran HDTune and did a deep check for errors and it was good. I don't know the exact model number but this is a WD 320GB drive and defraggler reports (after defragging) that there are 5 fragmented files left and they contain 46.2 GB of data and constitute a 41% fragmentation of the drive.

My first idea was to try to find a program that I can run from a bootable flash drive but I have been unable to find one so far. Any options?

Thanks:)

What are those files that are left over after fragmentation? Defraggler will show you at the bottom what those files are.

At least one of these is the pagefile, which I seem to remember is impossible to defragment. I know that some areas of NTFS cannot be defraged.

The system volume information folder contains system restore points and cannot be defragmented.

Yea, so it sounds like it is impossible for any tool to defrag these files. It is just weird that they are so large.

Well, I just had that happen on my 1.5TB storage drive, and that folder was over 80GB. I think system restore defaults to like 20% of the drive size, so it can get pretty significant after a while.

Yep you were right. I deleted all of the restore points and took care of that problem:)  42GB of restore points what a waste.

So there is no way to defrag the pagefile.sys? I found a program that could do it but it hasn't been updated for vista and 7...

Reading through the documentation of one of the defrag tools (ultradefrag, I think) they talked about a ntfs 'bug' which did not allow certain system files to be moved. I don't know if that meant that it was physically impossible without breaking the filesystem (you would have to doubt that because linux can resize ntfs partitions all sorts of ways) or if it was a barrier within windows, but they said they couldn't do it.
