Problem is: There are cool superblock magics for reiserfs. And for ext[23]. And even for good old Minix. Cool. However, there are also ugly file systems, such as fat for example. Fat has been defined as "something that can be read by a fat driver", which can be pretty much anything. You can't really detect whether it is fat. Even Microsoft only guess whether some FS is fat or not. And don't say detect it via a partition table. There are a lot of cases where you get absolutely no or wrong information out of it, and there are also lots of cases where you plainly have none.
