 1.) The error is completely harmless. "cp" probably tried to set attributes
     which FAT or NTFS filesystems don't suport.
 
 2.) Writing to NTFS volumes is known to be broken. From "man mount_ntfs":
 
      Warning: do not mount NTFS filesystems read-write.  The write support is
      not very useful and is not tested well.  It's not safe to write to any
      file on NTFS; you might damage the filesystem.  Unless you want to debug
      NTFS filesystem code, mount the NTFS filesystem read-only.
 
    I would therefore recomment to use NTFS only read-only at the moment.
 
 Do you have any problems besides the error message when writing to
 FAT32 volumes?
 
 	Kind regards
