1. NAME

ntfscmp - compare two NTFS filesystems and tell the differences

2. SYNOPSIS

ntfscmp [OPTIONS] DEVICE1 DEVICE2

3. 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

R 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

R ntfsinfo (8) for each reported inodes by the

R diff (1) utility.
