Did this with a PSOne. I bought a large X-in-one memory card, thinking it was a deal. I had a few games with different saves on it. I probably had about 5 or 6 different games and about 20 different saves.
Well, I had been playing Final Fantasy 7 and gotten to the end. I created the save point right outside of Sephiroth's location, and continued on to beat him and complete the game. Afterward, I turned off the console and did something else for a little while. But I couldn't get the song One Winged Angel out of my head, so I decided to load up that save and do it again.
No data existed. At all. On the entire memory card. All of my games and saves had been deleted. I learned that the memory card was not an official Sony product and couldn't be guaranteed. I threw away my card and bought an official Sony card. And from that day on, I always buy official products of the company. Be it memory cards, controllers or otherwise.
