Anyone know of a reliable way to shrink the size of the MFT in XP without installing a program like PerfectDisk or Diskeeper? The method most commonly given is to create a new DWORD value in the registry (NtfsMftZoneReservation = 1,2,3 or 4), but it doesn't work for me. I tried ControlSet001, 002, 003 and CurrentControlSet, rebooting each time but nothing. Is there more to it or am I doing something wrong? I can't believe there's not some easy way to do this. I would just use PD or DK but I've got one logical drive that even they don't work on.
