Thank you, you may have solved my problem. Not a big problem but it has been annoying me.
The MFT Zone is a large area which is supposed to be continuous with MFT so that MFT can expand into it without fragmenting. However on my drive the Zone is near the end of the partition, nowhere near either the MFT or the MFT-2 copy, as you can see.
Mft starts at 7278a (=468,874), so-called Zone starts at 9aac60(=10,136,672).
I've done the usual Registry machinations but nothing changes that misplaced zone. And anyway, I wouldn't want a gigantic dead zone in the fastest part of the drive.
Defragmenters all move the MFT and other system files to the fastest part of the drive, and leave a small pad after the MFT. That pad is the actual MFT 'zone' that NTFS uses. So I have really wanted to get rid of the useless Zone at the end of the partition - although it doesn't really decrease the available disk space, according to Microsoft.
You seem to have hit on a way I can accomplish this. .
I am going to try wiping free space. I'm hoping it will cause NTFS to reconstitute a smaller Zone in the right place. Thanks, I never would have thought of it and I believe it should work. (Can't do it right now, PC is too busy).
In the picture, the $ files, including $mft, are in the first 5 (red) squares. The MFT Zone is all that purple at the end.
