This'll probably be so much easier than you'd expect...

This is pretty much what I would expect. FAT doesn't know users, so it is
mounted as your current user. Ext4 knows users and the user information is
carried across mounts. IOW, for the ext4 partition, you simply need to run
"chmod -R adriano:adriano /media/Linux" as root, and it should then be owned
by your user across mounts (at least that is how it works for me).
I'm not exactly sure about the HFS+ partition as I have no experience with it.
Does it support user/group information in a way that Linux can use? (I'm
hoping yes, since OS X is a Unix.) If so, you could try creating a
subdirectory, chown it to your user and see whether the information is kept
across mounts. Or, you could simply make the whole partition world-writable.

No problem.
