I bought a 3d printer off Ebay which got delivered not too long ago, and it came with 2 sd cards - one with a build video and some demo print files, but worryingly another card that has all the previous owner’s personal files on there.
Not sure whether to format it, or to contact the seller offering to send the card back (free of charge)… how would you prefer to be approached in a similar situation?
Reach out to them and ask. The card is now yours, but the data is theirs.
I am sure if needed they can give you an online folder to upload the contents if needed.
Yeah I don’t see the need to return the card. But asking if they want the data seems sensible.
