The easiest way would most likely have been to attach the removable disc to the computer on which the library was created, and change the rights to make the library accessible to everyone. That way the library will be accessible even when you use the library from another computer with a separate login. Otherwise it shouldn't be accessible. It is a question of using the external drive and rights as intended.

This has nothing to do with win7 or win8. You can have the exact same problem in Linux if you don't use the rights in the filesystem correctly. And as was said earlier, FAT32 lacks all those rights. But it also lacks a lot of robustness.
