Recently, I acquired an External Drive with a terabyte of memory. Being the music geek that I am, I put all my favorite songs onto the External Drive. I managed to only put enough songs on there to fill up the entire terabyte of memory perfectly. However, a friend of mine decided to watch a movie on my computer. Now, I'm getting an I/O Error every time I try to access the External Drive. I'm guessing that the movie my friend watched downloaded itself onto my External Drive and it went over the memory capacity of it, I can't even get to the files to copy them or back them up. Does anyone have any ideas of or know how I can fix this? Because I'm definately running out of ideas.
