I guess if you see the partition type with fdisk and then try to mount 
the partition or activate the partition, it will tell you if it is 
formatted with the filesystem that it claims to be.

Other than that, I never thought to try any out of the ordinary program 
to figure out if it is setup with a filesystem. I did that for DOS, so I 
guess other filesystem presence would work the same.
