Comment 5 for bug 229000

I appplied the patch (thanks Agostino!) and tested it extensively:

- I used the fairly comprehensive POSIX test suite from http://www.ntfs-3g.org/pjd-fstest.html before and afterwards. Output was identical.
- Lots of random writes, unmount, mount, read, and check with diff that files are identical
- fill the device up to the last block and compare that everythign was written correctly
