Back up Failed with My Passport
I get the error message that Mac can't repair the disk My Passport. It said that I could open files on the disk but not save messages to it---to back up the disk and re-format it as soon as I can---but I have no idea how and fear that if I do anything I will lose everything! I ran first aid but it said it could not repair it. No idea why this suddenly happened---can it be fixed or should I just go buy another one? Thanks. Using a Mac Book Pro laptop.
MacBook Pro, Mac OS X (10.7.5), how do I fix????
