I needed this again and had a heck of a time finding it even on my own blog.
This thing is magic for fixing a flash drive with a faulty partition. My drive was installed and reported as working but would not show in explorer. It would show in drive manager but I could not do anything with it. Once again, Bootice fixed it for free with this little portable program.
I found this but have not tried.
