This is absolutely normal. When an NTFS partition is created, 12% of the
disk is explicitly allotted to the MFT, and any writing of data into this
area is impossible. The MFT is used to hold the critical index structures
from which files on an NTFS volume are referenced. However, if there is
insufficient free space on the system then the MFT is automatically reduced
in size.
System restore files are stored in the system volume information folder
which by default, is given permissions only for the System. You can take
permissions for the folder if you're using XP Pro and see the space used and
the kind of files contained in it.
There's no particular way to reduce the size of the existing allocation to
the MFT. And why would you want to do this. As files increase, the MFT
will be broken into even more fragments later and will seriously degrade
system performance. Please see if this article helps you -
