I don't think anything too bad has happened.
I lost a 70+ hour Secret of Mana save when I let a friend borrow the game. I told him not to blow in it or anything but when I tried to check up on my save it was gone...
Also, my first FF7 play through got erased because my sister was playing on a different save file and she accidentally saved over my 50 hour file (I was near Wutai). This was kinda dumb because she was playing on her file and it defaulted to save on mine.
ALSO! When I didn't know what the word 'format' meant in terms of memory space, I saw an option in the PS1 memory card menu to 'format' and I tried it out and poof! FFT Save gone, FF7 save gone, FF8 Save gone, Legend of Mana, etc... That was clearly my fault though. I thought that might happen too so I wasn't too upset.
