need help with my script and ways how MyDefrag works

[hINDUs]

hi, i have made script for my partition, but i have a few issues
the script:

Code:

Title('Defrag P TF2 OK')
Description("Defragment P: for TF2 optimize")

AppendLogfile("MyDefrag_P.log","LogHeader")

VolumeSelect
  Name("p:")

VolumeActions

  AppendLogfile("MyDefrag_P.log","LogBefore")

  ReclaimNtfsReservedAreas()

  FileSelect
    SelectNtfsSystemFiles(yes)
  FileActions
    PlaceNtfsSystemFiles(Ascending, 0)
    AddGap(RoundUp(ZoneEnd, VolumeSize * 0.0001))
  FileEnd

  // ZONE (2) Directories "no files".
  FileSelect
    Directory(yes)
  FileActions
    SortByName(Ascending)
    AddGap(RoundUp(ZoneEnd, VolumeSize * 0.0001))
  FileEnd

  // ZONE (3 - gcf, 4 - old, 5 - the rest)
  // all .gcf (big one's too!)
  FileSelect
    DirectoryPath("p:\Steam") && FileName("*.gcf")
  FileActions
    SortByName(Ascending)
    Defragment(Fast)
    FastFill()
  FileEnd

this partition is 165gb, non-system, mainly games, media files and work files. it is 95% full all the time, only got a few GB of free space
i wanted to run Steam and in particular "Team Fortress 2" Steam game as fastest as possible, defragment all the files and have them in their zones
the script is slow as it moves all the data on partition on every time (i run it every few weeks)

this script is far from ideal, i change it a lot, but i think it works for me ... but... :

firstly: when defragmenting big files (1-4 gb, they are in there's zones, but fragmented, or not its "right" place) MyDefrag moves them to biggest gap available, then smaller and smaller, ending with moving 4kb chunks (the cluster size) - what is painfully and horribly slow (the speed drops from 10-50 MB/s to 4-20KB/s) - how to stop this moving at, let's say 1mb chunk size? , or to speed it up?

secondly: when its processing some of the last zones (9-11), it's very often "giving up" and leaves files fragmented (red) - when closing MyDefrag and running it again, it defragments this files successfully but again, a few minutes later it again "gives up" and leave the file fragmented... (thats why i have there MaxRunTime(5 minutes) statement - i run MyDefrag in a loop to fully defragment this zones, also that's why i got such much crap commented out in these zones - i have to try different things to get this zones to fully defragment. no files on this partition are in open state, are not used, AV software is off) - how to force MyDefrag to not "give up" on those files?

- how to force MyDefrag to use the "NTFS reserved area" (dark blue)

any discussion about this script, how to improve it, and the ways how MyDefrag works is greatly welcome and appreciated.

Hi,

I have few questions:

Why do you insist in defragmentation of such huge files, especially if comparable with remaining free space ?
Have you evaluated gain what you get for such effort ?

And why do you run defragment + fastfill after sorting ? If 4 GB files gets wrapped around a temporary locked files, it will be moved again.

Sorting, Defragment() without fast/chunksize and shuffling by Fastfill comes to you with a big price -time and disk moaning.

You have too many fileactions in the zones, like

     SortBySize(Ascending)
     Defragment()
     Defragment(ChunkSize(100))
     FastFill()
     FastFill(WithShuffling)
     ForcedFill()

It is like shooting, poisoning, burning, throat cutting, stabbing and window falling of the same person to be sure it is dead.
I am afraid you will get extremely ( this forum likes this word, I do not, but this time I make exception ) low gain for extremely high effort.

Before applying actions, think twice :
What they really do ?
What is their intention ?
How they interfere ?
What is their gain ?
what is effort needed ?
Are they balanced ?
What is stability of result ?
Is all that torture ever worthy to do that ?

- how to force MyDefrag to use the "NTFS reserved area" (dark blue)

Just move it away. You can easily do so by changing the PlaceNtfsSystemFiles statement to PlaceNtfsSystemFiles(Ascending, 1MB). Then remount the volume (by running chkdsk or restarting) and the reserved area is (almost) gone.
You should also consider placing the MFT and directories further into the volume (about 3GB) for a better access time (see the MyDefrag standard scripts).

I agree with poutnik. You won't feel a performance difference with a not fragmented file and a file that is in 2-5 fragments which are close together (wrap around fragmentation from the SortBy actions). Trying to defragment everything on an almost full disk means a lot of work for the disk and is very time consuming. Also note that ForcedFill() strongly fragments files again.
