Do defraggers do a CHKDSK first?

Does a defragger, such as PerfectDisk, perform the equivalent of a
CHKDSK before defragging?

If not, then should I be running CHKDSK before every defrag?

Actually, you should run a backup before defragging. Although
the process has become more reliable.

I'm looking for a defragger which works the way the old Norton
Utilities defragger did. The old NU program also MOVED directories
and files so that there was no free space at one end of the disk. This
gave you one very large free space, minimizing the change for new and
changed files to themselves be defragged. Why can't Diskeeper do
that? I know they could, they just seem to imply it's not necessary.
Do they think we are that stupid?

I think it has become impractical in this day and age to move such large
amounts of data around on the disk. That might have been practical in
the old days, but nowadays with 100GB disks being considered small, it
would take days to defrag a single disk in that manner anymore.

I think you are right in the mark with that last statement.
I also think that most computer users would not even understand
what you are talking about.

So, they thing "we" are stupid, and I fear they are right.

With a modern filesystem you're actually better off with interspersed
free space, ensuring that when you append to existing files the fragment
created is physically close to the existing file.

This also allows newly created files to be placed near the existing
content within the directory.

The only case where you don't want interspersed free space is when the
drive is exceedingly close to being full, in which case you can't
effectively defragment anyway so the point is relatively moot.
