    exfat: retain 'VolumeFlags' properly · 7018ec68
    Tetsuhiro Kohada authored
    MediaFailure and VolumeDirty should be retained if these are set before
    mounting.
    
    In '3.1.13.3 Media Failure Field' of exfat specification describe:
    
     If, upon mounting a volume, the value of this field is 1,
     implementations which scan the entire volume for media failures and
     record all failures as "bad" clusters in the FAT (or otherwise resolve
     media failures) may clear the value of  this field to 0.
    
    Therefore, We should not clear MediaFailure without scanning volume.
    
    In '8.1 Recommended Write Ordering' of exfat specification describe:
    
     Clear the value of the VolumeDirty field to 0, if its value prior to
     the first step was 0.
    
    Therefore, We should not clear VolumeDirty after mounting.
    Also rename ERR_MEDIUM to MEDIA_FAILURE.
