Let me tell you about what happened to me a few days ago. I had some important files to take to work and I really mean it when I say important. I put those files on my USB stick and when I wanted to open them at work, the files were gone! I panicked and I did not know what to do. A co-worker helped me a lot. He told me to watch a great and very helpful mac usb recovery video. I did that, I watched the video and I found out how to recover the deleted files. Luckily, the files were back on my USB.
