Unmoveable data.

By jardinier ·
When running defrag in any version of Windows, one encounters randomly positioned clusters designated as "unmoveable."

Can anyone enlighten me as to what type of files/data is contained in these clusters, and why this data is "unmoveable?"

Unmoveable data.

Hi,
This is an excerpt from knowledge base article 227350 you can find it at microsoft.com/technet by searching on that number.

"The following files are unmoveable system files. They are always displayed in green in the defragment analysis display:
NTFS Master File Table (MFT) and Reserved MFT Zone: Usually contiguous at the very beginning of a NTFS volume but can become fragmented if many files and folders are added to a volume.
NTFS Master File table Mirror (MFTMirr): Usually located in the middle of a volume and is already contiguous.
Virtual Memory Paging file: Used for temporarily swapping pages of memory to disk"

Hope this helps..

Agree with beer monster. If you run defrag and want to optimize contiguous space, try disabling virtual memory. This will remove the swap file from your hard disk temporarily and free up the space. When your done with your defrag, re-enable virtual memory. Keep in mind that if you disable VM your machine will run more slowly. If you plenty of RAM this shouldn't be a problem.
