Default defrag improvement.

A phenomenon I have observed in Windows XP is that when I compact in =
Outlook Express before running Disk Defragmenter then file fragmentation =
is less when Disk Defragmenter analyses the disk.

Hope this helps.

Guys...

I know for a fact if you want to write sector by sector from the =

beginning
to end of an hard drive, it may be very fast.
=20
Defrag is very slow indeed.
=20
I am wondering if there is some optimization that can be made to the =

defrag
so that data is pre-prepared in memory (just the meta data of course), =

and
once those pointers are ready, a major one-time-only set of writes =

occurs.
=20
the problem I think with the slowness of defrag is that it moves =

blocks back
and forth.
=20
I know I know, defrag must keep the disk consistent so it can not do a =

one
time operation otherwise a power failure may screw it all up....
=20
but what do you think ?
