ntfscmp - compare two NTFS filesystems and tell the differences
ntfscmp [OPTIONS] DEVICE1 DEVICE2
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 devel-
opment 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
The terse output of ntfscmp is intentional because the provided infor-
mation 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.
Below is a summary of the options that ntfscmp accepts.
