Most likely a file named "$RWX9LVZ" is not really
owned by a user. Possibly a temporary file being
downloaded (or uncompressed, or whatever). It is
even probably a hidden one if you cannot find it
through Explorer.
As a consequence, there is probably no point trying
to assign it to a user also defined on Linux.

Ok, this would help.
The problem is that usermap scans the partition and
finds files (such as system or package files) whose
owners are not real candidates for Linux accounts.

It is ofter easier to get each Windows user to create
on Windows a file in his/her home directory, then use
secaudit with option -u to display the owner and group
SID of the files, then concatenate the outputs and set
the matching uid and gid :
On Windows :
secaudit -u sample-file
On Linux, on a mounted partition
ntfs-3g.secaudit -u sample-file
On Linux, on an unmounted partition
sudo ntfs-3g.secaudit -u /dev/partition sample-file
Files which are not created by users generally do not
need to be assigned to Linux users. They just appear
to be owned by root. You probably may ignore undecided
SIDs if all your real users are mapped.
Note : for the mapping to be possible, the grouping of
users must be the same in Windows and Linux.
By default Windows 7 puts all the users in the same
group, and Windows 8 puts each user in his own group.
