You should also look around more here on the board. :) http://www.msfn.org/...yresume-issues/ That is the reason that Andre only recommends the use of MS's own defragging tools. As you found, defragging just to eliminate fragmented files is only part of the solution. File placement is also a factor.


A very, very useful link. Many thanks.

To paraphrase bphlpt: Windows since 98 does know which files are loaded in what order because a special task observes this. Windows' defragger uses this information to optimize file placement on the disk and reduce the arm's movements.


Hey, I did not know that. So defragging is best done by Window's defragger then.
Many thanks for this tip to pointertovoid and bphlpt,

NOT really "necessarily", tools like Mydefrag (there may be others :unsure:):
http://www.mydefrag.com/
use similar techniques and - more than that - allow to experiment with different approaches thorugh a scripting-like language:

As always, tests need to be conducted but I wouldn't swear that the MS built-in strategy (whatever it is) is actually the "best possible", there may be room for further optimizations.

Many, many years ago, the world motocross champion was a belgian guy

Not so "many many" years ago (I truncated the quote on purpose :D ), but It seems an other country has taken over recently indeed (scroll up few lines). 2008 can be seen as an arguable transition phase.
However, if you remove the engine... we're still ahead ! :)

And now Antonio Cairoli has 6 Championships, becoming the all-time 2nd together with Joël Robert and after Stefan Everts.
