A problem I've only ever had with Sony

[-Samurai-]

I've never had such problems. Hell, all my data on my PS1 memory card is still intact. Same for my PS2 cards.

I've never had a problem with my memory stick for my PSP either. It gets used tons because I switch it from PC to PSP to PS3(yay memory card slots).

 

[Why do I care]

Sony never really screwed me over. All my memory cards never screwed me up and always worked how they should. My little complaint is that those 3d tv's they got are tooooooo damn expensive.
