wasting time! Grrr!

I downloaded a lot of pictures last night and deleted them from my camera so I thought I'd burn them to CDs. The first one said it was created successfully, the second one didn't, so I made 2 copies of the first because there was a movie Graham made and I wanted to send it to him. But now Toby won't read any of those 4 discs or one I'd made another time--I don't know if the discs are blank/ruined or there is something wrong with Toby and meanwhile I've wasted all this time dorking around! AK!
