Full Discussion: Directory Inode Number Not Unique

A directory is essentially a file, one that is written in a very specific manner. And for all files, the only data structure that will give out complete information about the file is the inode. So, for all files there is only one inode, unless the file is a link. In that case, you have two or more files referring to the same inode.

Of course, the inode number is unique only on the filesystem where the file exists. Files across different filesystems can have the same inode number.

The directories that you saw were probably across different filesystems.

ntfsinfo

NTFSINFO(8)						      System Manager's Manual						       NTFSINFO(8)

NAME

       ntfsinfo - dump a file's attributes

SYNOPSIS

       ntfsinfo [options] device

DESCRIPTION

       ntfsinfo will dump the attributes of inode inode-number or the file path-filename and/or information about the mft ( -m option).  Run ntfs-
       info without arguments for a full list of options.

OPTIONS

       Below is a summary of all the options that ntfsinfo accepts.  Nearly all options have two equivalent names.  The short name is preceded	by
       - and the long name is preceded by --.  Any single letter options, that don't take an argument, can be combined into a single command, e.g.
       -fv is equivalent to -f -v.  Long named options can be abbreviated to any unique prefix of their name.

       -F, --file FILE
	      Show information about this file

       -f, --force
	      This will override some sensible defaults, such as not overwriting an existing file.  Use this option with caution.

       -h, --help
	      Show a list of options with a brief description of each one.

       -i, --inode NUM
	      Show information about this inode.

       -m, --mft
	      Show information about the volume.

       -q, --quiet
	      Produce less output.

       -t, --notime
	      Do not display timestamps in the output.

       -v, --verbose
	      Increase the amount of output that ntfsinfo prints.

       -V, --version
	      Show the version number, copyright and license.
