I was shooting today, spur of the moment and had no extra card with me. And wouldnt luck be hold, my cf card crapped the bed and I lost many a great shot, Im so sad and disappointed with myself I wanted to cry (were talking a 45 year Mason ceremony for my Grandfather). Anyways. A friend of mine says the other day after reading my card in his computer to get some pictures, you dont format your card. Im like no, why would I?? I just erase them and start shooting again. So today after unloading some pictures I format the card before I start shooting again. I shot around 50 pictures with no problem. Fired the camera up tonight to shoot some of the shots, and low and behold, I love memories. Now I cant get the card to do anything, it wont keep pictures, and when I try to reformat it, nothing, locks up error 99. What gives. Can I reformat the card another way?? Sorry about the long thread, thanks the help though, I appreciate it, and will never bring my camera without my gear again!!!
