** Description changed:
[Impact]
OEM customers raise this issue, thinking that the error message can be
misleading to inexperienced users.
[Fix]

[Test Case]
Format a SD card with NTFS, lock the SD card as write-protected, insert the
card into the SD card slot. If the card is mounted as read-only, the bug is
fixed.
[Regression Potential]
+
+ The fix posted looks shouldn't cause regression.
[Original Report]
Mounting of read only NTFS filesystem gives a following error popup:
Cannot mount volume.
Unable to mount the volume '<Volume name>'.
Details:
Error opening '/dev/sdb2': Read-only file system
Failed to mount '/dev/sdb2': Read-only file system
I believe this should be mounted as read-only instead of an error
message.
Mounting by hand with the "-o ro" argument works as expected.
