My niece has a macbook and an external disk which ended up being connected to a pc. The person doing that did something so when she opens up the disk on her mac nothing comes up and when I open it on my pc the disk shows up, gets a drive letter but an unreadable filesystem (which it asks me if I want to format it).
If it were a ntfs or fat volume I would know what to do but with a mac I'm a bit lost.
