Fujifilm xD-Picture Card 16 MB

it came to me used I understand but when put in the camera it showed pic from previous owner and after I deleted all pictures it told me the card needed to be initialized which I did not know what that meant till I googled it and basicly it comes down to that the card is either old or dirty and can’t be used no longer……GREAT Thank you very much on the info to format it to my camera this did fix the problem and it is working fine thank you so much for the tip!!!!!
