Hello, What is the least drastic measure for recovering from an application file i/o error? I have one mp3 file I have been listening to all week, and suddenly today, it will not play. It starts, plays for about 3 seconds, and then starts over at the beginning, and continues looping. Pressing 3 to move to the end of the file does not help, nor does navigating out of the folder and back. The other mp3 file is chapters 2 through 10 of the Harry Potter book. I had trouble with the whole book before, so tried to downsize, but even though I was listening to this book earlier today, now I am hearing the "application file i/o error" error message when I attempt to open it. I tried moving this file to another folder, to the root directory, and back to its original folder, but still get the error message when I attempt to open this file, no matter where it is. If at all possible, I'd like to avoid reformatting the flash card. I've only got 200M worth of files on it, but it's bothersome having to transfer all that material back if I have to reformat. Any other possible solutions out there? I already restored the defaults with 2+B, and that didn't help. Thanks, Jeffrey
