I formatted about seven cds and put data and pictures on them with my Dell computer. I popped the cds out and put them back in to make sure the info was still on them before I deleted it off my computer. When I put the new cds into my Toshiba, nothing shows up on the cds. I can look at the back of the cds and tell there is something on them. Is there a reason they won't show up on any of the computers I've tried them on??? Please help! I am very sad to see all of my work gone!
