I am new to the Apple World and want to use my external hard drive on my Macbook Pro and Desktop HP PC ? It is currently formatted in a Mac way , but now it doesn't work on my HP . I want to be able to use it on both of my devices as I have information on it which I need for working on both of the devices . I hope somebody can help me , because my nearest Apple Store is an hours drive from me .
Thanks in advance.
