Noncontiguous blocks in ext2 filesystem


Hi,

I have previously installed a fglrx driver for my Radeon Mobility M9 card in my Redhat 9. Unfortunately, this caused a lot of system freezes and I have to improperly shutdown my laptop. (I have removed this driver since then...) So, whenever I reboot my Redhat, it forces an fsck of my root directory (which is an ext2 partition). After the first fsck, it asks me to reboot my machine. After the 2nd reboot, I can successfully startup my system.

But one thing I noticed is that everytime it finishes with fsck, it displays a message that goes something like (**Sorry but I dont have the exact message right now)...

***********************************************
clean: (<certain numer>/<certain number> files) (1.5% non-contiguous)(<certain number>/<certain number> blocks).
************************************************

I learned from the net that non-contiguous blocks actually mean de-fragmented blocks. What is its impact on the system? Is there any tool available to de-frag my partition? Although I was able to reboot my machine, I am not that confident that everything is OK...Can someone share some insights on this message?

Thanks!

Question

so if i interpret the link correctly, it should be understood that the x% non-contigous does not mean that inodes are no longer properly linked.

ie. eminent system failure is unlikely to result.
