Does it now show more free space?
I had the same problem that angus528 was having.
After following Dack's instructions (thank you a million times over, by the way) I was able to see and even play all of my games. I noticed that my drive was showing almost no used blocks (although I have over 120 games on the hard drive). I figured that this was okay and was hoping that upon loading another game on the WBFS partition the size problem would correct its self.
I was wrong.
The next game that I loaded actually corrupted the first game on my WBFS partition. I believe this was due to WBFS Manager thinking that the space was free to use up. I did a little more research and found another tool that can inspect the WBFS partition called
Wiims WBFS Tool. This tool exposed that all games loaded were "invalid" and that 2 of my games were even sharing sectors on the hard disk. (my ill fated post recovery added game along with the first game that I ever loaded. Thankfully the first game was larger than the new game, because I am confident that I would have corrupted more than one title had that not been the case)
Upon running: (Please read the documentation before blindly running these commands as this is a very powerful tool when it comes to managing the WBFS partitions)
