How to set Master File Table Zone Reservation in XP

Run regedit

 [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ FileSystem]

Under this key there is a setting called NtfsMftZoneReservation, the default setting of which is 1.

The range of this value is from 1 to 4.

The default setting reserves one-eighth of the volume for the MFT.

 A setting of 2 reserves one-quarter of the volume for the MFT.

 A setting of 3 for NtfsMftZoneReservation reserves three-eighths of the volume for the MFT and setting it to 4 reserves half of the volume for the MFT.

Most users will never exceed one-quarter of the volume.

A setting of 2 for most users. This allows for a "moderate number of files" commensurate with the number of small files included in most computer games and applications. Reboot after applying this tweak.
