I'm trying to move the MFT during BootTime with Ultimate Defrag 4 in Vista. I can move it to an empty area in the middle of the disk, but when I try to relocate it within the data, it starts clearing free space for the MFT, it gets to 34% then quits with an error: CAN'T MOVE $MFT. I ran CHKDSK and it corrected some issues with the file system but it still doesn't work. I've used this program to move the MFT in XP and 7 and it always works flawlessly. Would anyone have any idea what might be causing this? I wrote customer sevice at DiskTrix but I'm using a demo version so I'm not sure they'll even reply. Thanks.
