WD My Passport 1Tb Corrupted files

I just made an archive full of video ciips from my Canon T2i 550D. Next morning I tried to open the file but it was unreadable. I can see everything else except those files…

How can I recover or fixed corrupted files on a MAC OS X 10.6.8???

Hi, your files might be corrupted or hidden, check the link below for the steps to show hidden files. If the files are corrupted you can use recuva or teskdisk to scan the passport.
