I must confess Wubi were awesome for all ms-windows users are still not that comfortable when working with partitions, which usage makes me recall the good old times i used BeOS-5 PE, which works in similar way.
The problem is it seems to have a difficult or impossible access on the ntfs or fat32 filesystem where it were installed, situation can be considered hugelly annoying for the most of the Wubi-Ubuntu users...
As well, there is no information if fuseblk and ntfs are the same thing, or which are the differences among both.
