howto: cause HD fragmentation on demand

ok this might seem silly..

we all have our favorite utilities to DEFRAG the hard drive.

but what if you want to do a comparison between products.. after the
first defrag -- the next product has an easy job.

SO... I am looking for a method to re-introduce fragmentation to the
files on the HD. Controlled % would be best, but random would be ok.

I have tried copying lots of small files, copying large files, deleting
files... but there has to be a better way.

Ideas?

Outlook Express newsgroup message uncompacted make quite a splash. A few
System Restore points for good measure.

Open up and run several different programs say about 20,then pull the plug
for your computer out of the wall. :-)
I hope you know that I'm kidding?

That won't cause fragmentation, it will cause lost clusters, requiring a
chkdisk.

I would suggest that for a benchmark test an image made with disk-imaging
software would be more repeatable. The image should be made in literal
cluster-by-cluster mode to avoid the process introducing its own
defrag-effect.

HST, my experience is that defragging has very little effect on modern
computers.

Please go ahead and try it...prove me wrong.

If I were doing this then I'd create a new partition from the free space
on my (largest) disk. Then I'd copy files into it in a sequence
guaranteed to cause fragmentation. Then I'd backup the partition to a DVD.

This way, after each test, I can restore the partition to precisely the
state it was in before (you might have to be careful which
backup/restore program you use; if the restore is just logical, at the
file level then you won't achieve much).
