Laptop with Disk errors

I have new laptop that will not defrag properly. I am trying to clean it up so I can partition it and get it to boot faster . I have used O&O defrag with the option to check the disk for errors. It says it is running chdsk and after 61% it starts finding index errors and displays these.

I then run chkdsk myself and let it reboot as it wants C: to itself and it finds no errors at all. Run the defrag and the errors are there.

If I run the defrag without the check it runs for nearly an hour to about 40% and then jumps to 100% and all done and the drive is no better that it was. It says 7 files fragged with 28% fragmentation. It is really slowing down the boot times.

What happens if you defrag using Vista's tool?
*EDIT * r u using the 64-bit O&O? What version #?

Yes using the 64bit version. Using V8.6 of O&O defrag as I was told later versions do not work the same and does not help FSX in anyway. It certainly works fine on my other desktop PC.
Tried using the Windows Defrag and it was going for hours and when I cancelled it and took a look it was no better than when it started.
This is not a slow machine with 6GB memory and a C2D 9700 CPU at 2.8Ghz so would not expect it to take to loong to defrag 85GB of files on C

Well finally got the issue. It was recovery points. My drive usage had gone to about 130GB for just a fresh Vista Ultimate 64 install. Tracked down the issue using a cluster inspector and saw all the huge files in System Volume Information.
Turned off restore and wham the drive space was back, the errors gone, and the defrag that actually worked.

Very good!
