I agree with peety3. This is kinda like motorcycle helmets, or baby car seats. Once they have been in a car accident, you are supposed to replace those safety devices even if they look OK. You never know what little crack or defect has developed that you can't see.


While not quite as important as personal safety, photographing with a potentially damaged card is just a ticking time bomb. You never know when that one critical photo lands on that one little defective spot on the CF card, and the image becomes unrecoverable.
