Fat32 doesn't appear to support FSInfo

[Yazwh0]

The FAT32 implementation doesn't appear to implement the FSInfo structure.

The link seems broken.

Strange, its working for me!

Have a workaround by calling this after each update.

    public void UpdateFsInfoFreeSpace()
    {
        var p = _data.Position;
        _data.Position = _bpbFSInfo * SectorSize;
        var fsInfo = StreamUtilities.ReadExact(_data, SectorSize);

        var usedSectors = UsedSpace / SectorSize;
        var freeSectors = TotalSectors - ReservedSectorCount - usedSectors;
        fsInfo[488 + 0] = (byte)(freeSectors & 0xff);
        fsInfo[488 + 1] = (byte)((freeSectors >> 8) & 0xff);
        fsInfo[488 + 2] = (byte)((freeSectors >> 16) & 0xff);
        fsInfo[488 + 3] = (byte)((freeSectors >> 24) & 0xff);

        _data.Position = _bpbFSInfo * SectorSize;
        _data.Write(fsInfo, 0, SectorSize);

        _data.Position = p;
    }
