I was told once that memory cards do wear out....kind of like a video tape being tape over so many times, eventually the quality goes kaput. Is this true? The reason I ask, a friend sent me pics from her camera and she is haivng problems....mostly streaks thru all her pics, i have never seen anything like it before in 15 years of photography....having gone over her camera and pics thoroughly, that is all that i could come up with. Since I am quite new to digital, I need your folks help!!! Sorry, i dont have the pics anymore to show you. thanks, Kim Please feel free to move this thread to the correct forum if i'm not there.
