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 verifi-
cation 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 informa-
tion is enough in each case to determine the exact differences. This can
be achieved, for instance, if one compares the verbose outputs of ntfs-
info(8) for each reported inodes by the diff(1) utility.
