Optimise NTFS

You can negate this a little with the following tips:

* By default NTFS will automatically update timestamps whenver a directory is traversed. This isn't a necessary feature, and it slows down large volumes.

Disable it by pointing regedit to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem and set 'NtfsDisableLastAccessUpdate' to 1.

* NTFS uses disparate master file control tables to store filesystem information about your drives. Over time these core MFT files grow and become fragmented, slowing down all accesses to the drive. By setting aside a little space, MFT's can grow without becoming fragmented. In the same key where you disabled the last access feature creat a new DWORD value called 'NtfsMftZoneReservation' and set it to 2.

Note:  This tweak will not work on FAT32 file systems!

    NtfsMftZoneReservation=2 can make a hurm to system performance. If u make your NTFS volume full, you will usually get a high fragmented MFT. MFT Zone is not a unmovable bufor. If disc is full it will reduced in half!

    This is a run-time parameter and does not affect the actual format of a volume. Rather, it affects the way NTFS allocates space on all volumes on a given system. Therefore, to be completely effective, the parameter must be in effect from the time that a volume is formatted and throughout the life of the volume. If the registry parameter is adjusted downward or removed, the MFT zone will be reduced accordingly, but this will not have any affect on MFT space already allocated and used.

    Hi Author, Thanks I forgot about this setting (I think a program called TweakXP also let's you modify it). You forgot to instruct users on what to do if the value doesn't already exist. According to Microsoft it's a new DWORD value. http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/regentry/46656.mspx?mfr=true Cheers, Christian

    1. Navigate to the folder specified. 2. Once there, right click and select "New DWORD Value" 3. Call it "NtfsDisableLastAccessUpdate" 4. Double click on NtfsDisableLastAccessUpdate and set the value to 1. Repeat the previous steps for the second DWord Value only change the name of it to NtfsMftZoneReservation and set the value to 2. Hope this helped! Tim :)

    Regarding the "NtfsMftZoneReservation" setting. The author has omitted important details. Space is reserved for the MFT even when using default settings - a space that is usually more appropriate than what the author suggests. Also, the results of making this change cannot be fully reversed if you later change your mind. Larry Miller, Microsoft MCSA.
