I know I read this somewhere but I couldn't find it, a few weeks ago my 512 card corrupted on me and no matter what I did I could not reformat it. I tried it in a card reader, through the PSP, and even through DOS commands but I couldn't get anything to recognize it :Argh:. So my question is if anyone knows exactly how to contact Sandisk to get it replaced. (Yes it is from Sandisk) I looked on their site but just found technical help and that sort of stuff, but I know someone managed to send it in and get a new one back for free. So thanks to anyone who can help, and yes I did use search :).
