Error? 

Windows probably doesn't tell you anything but you can configure logging on samba to see what it has to say. Perhaps Wireshark, too, to see what is happening.

That's not a work around, that's a fail. Bricks are storage for the GlusterFS filesystem just like spinning rust is for NTFS. You can't just wrote data blindly to some sector of your hard drive. You can't just write blindly to a brick.
