Hi. When I plug the Mac passport in to my Samsung google chrome notebook it no longer reads it. It does acknowledge USB drive and that it can not read and needs to be formatted. I have video footage and audio from 3 months of shooting a webseries that has not been edited yet. What would have if I allowed the google chrome book to reformat the passport? It's the holidays do I go ahead or wait 2 days to take it in to a place like geek squad. I'm novice when it comes to these things.
