I have a late 2013 27" mac with 1TB Fusion drive. 3.5 GHz I work constantly on Photoshop with large files and have been using a Buffalo DriveStation DDR High Speed 2TB but in the last month it kept ejecting sporadically while I was working. YES, I should have swapped out the drive right then! Now the drive ejects itself when I click on it to select it and I cannot access the data. TimeMachine stopped backing up anything from it on Feb 1st so there is one month of work I need to get off the drive. I have run it through the Disk Utility Verify and Repair multiple times yesterday and this cannot be completed because it ejects. At first it showed the partition with an odd name like Disk382 then it shows the name I gave it, "Data" then it ejects. Today I tried a program called TestDisk using Terminal and it can see the drive, but again when I selected it, it ejects. Does anyone have any ideas of what else I can try. ALSO, would you recommend that I take the drive to Apple Genius Bar? I've never had to rely on someone else to fix my computers and read that Best Buy is terrible. Thanks in advance for any help on this!
