Let's set component to Unknown until somebody performs an investigation.
Alexandre Julliard already found teh bug to be in kernel32.dll/volume.c based on the floppy immage I provided. That's why I updated the component originally. The FAT super block reader had considered a FAT12 set to only 1 sector/cluster to be unreasonable, but that's exactly how a floppy diskette is typically formatted!
I leave it to him to update the status to CONFIRMED when appropriate.
