My computers has been showing image files (mostly dng and cr2 files) as damaged. I've attached a few examples of what's happening below. It's definitely a problem on the computer, because the files look fine on other computers and it happens to images from a variety of cameras and hard drives. I've spent all night going through the process of uninstalling and deleting all adobe cs6 software and installing a trial version of creative cloud, but it didn't solve anything. Sometimes a file can be fine as a cr2, but then when converted to dng it is damaged. Sometimes there's only a few corrupt images in a folder, but when I visit that folder the next day there are twice as many damaged files. I've also gone through the process of verifying my hard drive on disk utilities with no errors. My computer is a 2011 27 inch iMac (only purchased just over a year ago). All the software and operating system is up to date. Any advice would be so greatly appreciated. I'm freaking out slightly.
