Does anyone know how to reduce the size of the MFT reserved zone below the current 12.5%?
I have a 150gb HDD, 54gb already used and my MFT file is 120mb.
I find it a little silly that my reserved zone has to be nearly 19gb when my MFT is only 120mb when my HDD is 1/3 used.
I know it wont speed up my computer or anything, because that 19gb isnt actually being used, its just a safety net, but i was just wondering if its possible to change it below the 12.5% standard

If you fill the drive Windows will reduce the size of the reserved zone so data can be written there. You don't want to squeeze the MFT on a too small area cause you can't defrag the MFT. More informations : http://www.teamapproach.ca/trouble/MFTMetadata.htm
To prevent the MFT from becoming fragmented, NTFS reserves 12.5 percent of volume by default for exclusive use of the MFT. This space, known as the MFT zone, is not used to store data unless the remainder of the volume becomes full.

Depending on the average file size and other variables, as the disk fills to capacity, either the MFT zone or the unreserved space on the disk becomes full first.

* Volumes that have a small number of large files exhaust the unreserved space first.
* Volumes with a large number of small files exhaust the MFT zone space first.

In either case, fragmentation of the MFT occurs when one region or the other becomes full.
