By default on a freshly installed system with plenty of free space on a disk, where are the NTFS reserved area located on the disk? What percentage of the way through the disk is it located at? Under any conditions does the reserved area move? Are there more than one reserved areas?

Is it different on Windows 7/8/8.1 or Server 2008r2/2012/2012r2?

I'm using MyDefrag and would like to make it put the MFT and other NTFS files actually inside the area Windows reserves for them just before the area reserved for their growth.

Edit: From what I can tell the below MFT locations (from fsutil) are their cluster number, but the length is in bytes (in hexidecimal).


NTFS Volume Serial Number :       
Version :                         3.1
Number Sectors :                  0x00000000253f97ff
Total Clusters :                  0x0000000004a7f2ff
Free Clusters  :                  0x00000000018aecb2
Total Reserved :                  0x0000000000000760
Bytes Per Sector  :               512
Bytes Per Physical Sector :       4096
Bytes Per Cluster :               4096
Bytes Per FileRecord Segment    : 1024
Clusters Per FileRecord Segment : 0
Mft Valid Data Length :           0x00000000197c0000
Mft Start Lcn  :                  0x00000000000c0000
Mft2 Start Lcn :                  0x0000000000000002
Mft Zone Start :                  0x0000000000b4c1e0
Mft Zone End   :                  0x0000000000b4ff20
RM Identifier:

Though I'm a little hazy as to their meanings. At the Lcn 0xC0000 there are 4 "MFT Locked Clusters" and just before the Lcn 0xC0000 there is an empty cluster and just before that is the file C:$Bitmap, however the C:$MFT file is just before the Mft Zone Start location 0xb4c1e0.

By default on a freshly installed system with plenty of free space on a disk, where are the NTFS reserved area located on the disk? What percentage of the way through the disk is it located at? Under any conditions does the reserved area move? Are there more than one reserved areas?

Is it different on Windows 7/8/8.1 or Server 2008r2/2012/2012r2?

NTFS files do not go inside the area reserved for their growth

Where on the disk is the NTFS reserved area?
