I won't bore you with the details, but I did a clean install of Yosemite and then had some problems with my Time Machine backup, time machine didn't recognize it, and I couldn't mount the sparse bundle. I managed to get most of my data out using DiskWarrior, but I am missing about 1/2 my music, which I can get off of my iPod. It seems like everything else is back, but Im not sure. The only other thing I'm mainly concerned about are my photos. So that brings me to my question. Is there any way to easily see if all the photos in iPhoto have full size versions? I know it uses thumbnails for the previews of every image, so even though it looks like all of my images are there, I'm worried that some might just be thumbnails. iTunes was easy to figure out which tracks we're missing, they all had !s next to them because it couldn't find the original file. How can I make sure all my photos have full versions? Sorry I guess I did bore you with some details.
