Why is my camera showing error code C:13:01?

@agbor this error happens because of a bad connection between the contacts of the memory card and the camera. Try the card in a memory card reader and see if it works, also backup all your files. Then try to clean the contacts of the card with a pencil eraser. You also want to insert and remove the card a couple of times to see if it starts making proper contact. Wiggle the card a few times to see if the error will disappear. Ultimately you could also try a new memory card.

for me it was just the "lock" switch on the memory card. I had really forgotten that some cards have these.

I have the Sony Cyber-shot DSC-P52 that I gotten from I think the thrift store an I got the same message and I don't know where to buy new memory stick at if they still make them for that camera anyways I tried everything I could think of and nothing work, can anyone tell what I could do plus know where to buy memory stick for that camera
