Running Disk Defragmentation failed in XP

[Romanus81]

I was running Window's Disk defragmenter, and it said it could not defragment two files:
From the error report:
Fragments (2) Size (9.77GB) \found.000\dir0000.ckj\home.virtual.disk
Fragments (3) Size (12.11GB) \wubi\disks\home.virtual.disk
Is it normal for these files to be fragmented, or is windows just mistaking it for a fragmented file? Should I use a different defragmenter? Will this have an effect on the speed of ubuntu?

Hello, if you installed ubuntu with wubi, I got the same message, If I am not wrong it is normal and don't worry.
