Hey, i was following Nick N's defragging processes using O&O defrag pro.  one of the steps involves using the offline defrag..  I have recently realised that this stage is not working correctly for me and i was wondering if anyone could help.  When the offline defrag gets to about 45% it stops and goes straight to 100% (not sure if it said there was an error or not).

Then it stated that four files could not be defragmented, possibly due to not having enough free contiguous space 

Im not sure what this means more room? its a 45 GB partition, there is 23.7 GB free! should be enough lol any ideas or any other defrag programs i could try?

I have completed multiple name and space defrags, here is what the CDrive currently looks like after analysis.  any assistance would be much appreciated.

Nick has been very helpful, he has been in contact with me once since his departure with some stuff to try but its going to take a while to get round to it.  So hopefully that will cure my problems!
