Hi,

apologies if this is not the right avenue of apporach, I've been unable
to find out how to register on the forums to raise an issue there.
Please point me in the right direction if a different venue is more
appropriate for bug reports.

I'm working on a project where a media with some data has to be prepared
on a Linux system to be read by a windows system. The media must not be
written to by the windows system, so I'm using SD cards (which have a
physical write protect switch).

It appears that a file system created by ntfs-3g on Linux (using
2017.3.23) cannot be read by windows from a read only medium. I'm using
the below test case:

On the linux system:

- Create MBR label on SD card
- Create partition (with parted), using fstype ntfs
- Create file system on partition with mkntfs
- Remove SD card from machine, and write protect using the physical
  write switch

On insertion into a Windows 10 system the following occurs:

- There are errors about errors on the NTFS file system in the event log
  (unfortunately I do not have the exact details, can deliver later)
- The partition is shown as "RAW" in Disk Management, but is assigned a
  drive letter
- chkdsk.exe recognizes the file system as NTFS, and reports no errors

When allowing write access to the SD card windows successfully
recognizes the file system and mounts it.

Is this expected behaviour?
