So i made a previous post about this faulty ssd i got so i had some personal files pictures of familly and such on it but after finding problems about it (ssdsamsungQVO870) i managed to auick format it but i never could manage to slow format it even using 3rd party tools such as partition wizard ... but now i got in contact with the seller he told me to ship it back to him and he'll send me a new one , but now im worried is a quick format not enough to fully delete the data i had on it could he use a software or something to bring the stuff back or am i being paranoid for no reason ??
