Disable NTFS Last Access Time Stamp
From D3xt3r01.tk
WHY
Optimization. It should make little difference or none but it should still use the hdd less.
HOW
When Windows accesses a directory on an NTFS volume, it updates the LastAccess time stamp on each directory it detects. Therefore, if there are a large number of directories, this can affect performance.
1. Start -> Run -> regedit
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
3. Create the "NtfsDisableLastAccessUpdate" ( without the quotes ) REG_DWORD if it doesn't exist and set it to 1
