Probably nothing that's unique to ext4 over ext3 or ext2. ext4
implements normal Linux permissions, while vfat doesn't. As a
consequence, your mounted ext4 volume will have uid and gid
permissions associated per-file and per-directory. If those values
don't correspond to the uid and gid values on the system you've
mounted it on, then your local system won't see you as the owner.

I don't remember off-hand how to override the ownerships.
