There is strange files access issue since v18 update. Some random
files on partition became inaccessible, can't be read or even deleted.
For example:

# ls -la
ls: cannot access 'NlsStrings.js': No such file or directory
total 176
drwxrwxrwx 1 root root  4096 Oct 20 10:41 .
drwxrwxrwx 1 root root 12288 Oct 20 10:42 ..
-rwxrwxrwx 1 root root  8230 Oct 19 17:02 Layer.js < this file is ok
-????????? ? ?    ?        ?            ? NlsStrings.js < this file is
inaccessible
...

To reproduce the issue try to mount a NTFS partition with deep
structure and large files amout. Then run on it some recursive file
command, e.g. 'du -sh', it will list all access errors.
Can't say what exactly causes it. Filesystem itself is not damaged,
when mounting it via ntfs-3g, ntfs3 <18 or in Windows it works
normally. The files is not damaged and chkdsk report no errors.
