NT becomes unresponsive during an NTFS disk operation such as a dir.

A. When you perform a large NTFS disk operation such as a dir/s *.* or a ntbackup :\*.* NT can sometimes become unresponsive because NT updates NTFS files with a last access stamp and if viewing thousands of files the NTFS log file can become full and waits to be flushed to the hard disk, this can cause NT to become unresponsive. To stop NTFS updating the last access stamp perform the following:

  1. Start the registry editor (regedit.exe)
  2. Move to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
  3. From the Edit menu select New - DWORD value
  4. Enter a name of NtfsDisableLastAccessUpdate and click OK
  5. Double click the new value and set to 1. Click OK
  6. Close the registry editor
  7. Reboot the machine

This should improve the performance of your NTFS partitions.

Below is an example or a .reg file that can be used to automate this:

REGEDIT4
;
\[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\]
"NtfsDisableLastAccessUpdate"=dword:1
