I have some pics in my iphoto which I took and out of the whole set one picture is now corrupt, and the bottom 25% of the picture is missing when viewed. (The bottom 25% is grey). I remember it being fine before, so it was not damaged from the beginning or anything like that.
I do have a backup also (on DVD), but I must've made the backup after the file was already corrupted because the backup JPG shows up with same 25% missing also.
Besides Apple's built in disk stuff, I don't really use any defragmentation software for OSX.
Would that fix my JPG ? Or are there any other solutions ?
