I've never had to reformat, but while playing Arcadia Legends with a Nyko 59 block ( like when I payed $150 for my system, BLAST THAT PRICE CUT!) I got several "Corrupted Data" messages while trying to save. After getting real pissed, I realized that the memory wouldn't be gone until I tunred the game off, so after a few more save attempts, everything worked fine. That's the only game it ever did it on, by the way. Also, I am currently using the Interact 64MB card . One night, while over at my friends house, he tossed thecard to me while I wasn't looking; it bounced off my forehead and hit the floor effectively splitting it in half. I was frantic; the entire front half of the casing was completely across the room. 3 minutes and some Duct Tape later, I plugged the memory card back in and *
Ta Da* Absolutely no memory loss. I've been using the card since August and its new incarnation "ol' Tapey" for 2 months now and it's still going fine. I guess I'm just one of the lucky ones.
