Fdisk and mount disagree?

One thing to keep in mind is that fdisk reports the partition type
you set when you create the partition, and mount reports the file
system type that was used to mount the partition. There is nothing
that prevents you from formatting a partition ext2 that is marked as
FAT32. You can also change the partition type after later. If I
remember correctly, there is a "magic number" in the file system
headers that tells what type of file system it is, and mount uses
that when you use the auto file system type.

Makes sense, since when I bought the disc it came preformatted
with FAT32. For consistency's sake, I guess I should use fdisk
to change the ID to something else.
