My hard drive just failed so I had to erase everything. Luckily, I had all of my files saved on my external hard drive. However, when I went to try and drag my pictures from my external hard drive over to the pictures folder on my macbook, I got a message saying 'Sorry, the operation could not be completed because an unexpected error occurred. (Error code - 1426)' I've tried searching forums all over and I can't find anything that fits my exact problem. Any ideas?
