NTFS external drive some folders not showing on Mac OSX; but okay on Linux

Not all files/folders, but only a few ones not showing.  

Since NFTS is read-only (by default) in Mac, as long as not reformatting the drive/ partition, those files should be safe, in theory.

This seems to be a real problem encountered by many people.

Reason unknown yet.  Some said chipset not fully compatible. 

Some other people said the file system might be corrupted somehow.  Because NTFS is Microsoft's proprietary file system.  

In case one wants to repair the drive, it must be done in windows, using the following command.

        chkdsk /f /r 

WARN: backup your drive before making changes.
