Can't access my Toshiba external drive on mac.
How do I access my Toshiba external hard drive without formatting it (I don't want to lose my files)? I formatted it on my old mac two years ago but it won't work on my new mac or any other mac. I can see it but it won't work. Is there any way I can access my files without having to format the drive?
MacBook Air, OS X Yosemite (10.10.5)
