Hi all!
 
When talking about the best defragmenting strategies, I've read more than one time the advice to run "consolidate free space" and then "system disk monthly", repeating these steps if necessary.
 
Just for example, here.
 
But when I do so (I repeated these steps two times), I've noticed that the "system disk monthly" script creates big black (empty) gaps inside the forced fill data created by the "consolidate free space" script.
 
Is this normal? I mean, is this (having empty gaps at the beginning of the disk) the best defragmenting I can obtain? Or is there any contraindication to run together these two scripts?
 
Moreover I'm under the impressions of a somewhat general slowdown in disk operations (boot times, programs load times).
 
Any hint is welcome.
 
Regards, Luca

Yes, this is normal. The script will place the MFT and the directories at 30% into the data on the disk, and create zones from the beginning of the disk with files used when booting, files used by the most used programs, regular files, and spacehogs (less important files that take up a lot of space). Between the zones it creates gaps for temporary files. For more information about all the script see Using MyDefrag

From another posting I see that you have enlarged your first partition, so now the harddisk heads have to travel further between data on the first and second partitions. This equates to lower speed. Make sure all heavily used data is on the first partition. From a speed perspective it is best to have only 1 partition, so MyDefrag can put everything in optimum positions.

Your numbers look excellent. For more information see Why does MyDefrag not perfectly optimize my disk?

The consolidation is only necessary if your disk is quite full.
