NAME

       ntfscmp - compare two NTFS filesystems and tell the differences

SYNOPSIS

       ntfscmp [OPTIONS] DEVICE1 DEVICE2

DESCRIPTION

       The  ntfscmp  program makes a comparison between two NTFS filesystems from all aspects and
       reports all variances it finds.  The filesystems can be on block devices or images  files.
       Ntfscmp  can  be  used  for  volume  verification however its primary purpose was to be an
       efficient development tool, used to quickly locate, identify and check the correctness  of
       the metadata changes made to NTFS.

       If  one is interested only in the NTFS metadata changes then it could be useful to compare
       the metadata images created by using the --metadata option of  ntfsclone(8)  to  eliminate
       the usually uninteresting timestamp changes.

       The  terse  output of ntfscmp is intentional because the provided information is enough in
       each case to determine the exact differences. This can be achieved, for instance,  if  one
       compares  the  verbose  outputs  of  ntfsinfo(8)  for  each reported inodes by the diff(1)
       utility.
