Well, firstly there's no such thing as a concatenated volume: it's a concatenated plex. If you have a volume with only a concatenated plex, and you lose a drive, then yes, you only lose the data on that drive. I've never tried it, but I suspect that fsck would have a hard time recreating the file system if any sizeable chunk is missing. In general, I'd expect that you lose your file system under these circumstances.
