By default, when a file is accessed, NTFS writes information to record when the file is last accessed. One of the often discussed ways to improve NTFS disk performance is to disable the NTFS last-accessed timestamp. This is discussed in many places: http://technet2.microsoft.com/windo...7f13-4ac3-8da8-48ebd60b44471033.mspx?mfr=true I've thought of disabling this, but am worried about potential impacts of doing so. Does Acronis True Image Home 10.0 use the last accessed time at all?Anyone know of other programs that use the last accessed time? Thanks.
