Hey new here and I have tried google and every search means necessary to try and find the answer to my questions. I have a SimpleTech mini external drive for my Macbook as Time Machine backup and storage and it has worked fine until today. When i plug it in it wont automatically show my files i have to leave the Finder open and then it shows the main folders. To see any files I have to click the particular folder and again leave it open for the files to load. This is usually about a 5 minute or longer (depending on how many files are in that folder) wait. Obviously not normal. I thought well I can run Disk Utility to see if it can be repair but when I do that it gets an error and says the disk is unmountable even though I havent opened anything from drive. I have just about given up and any advice would be helpful!
