I have a 1 G mp3 player from Hong Kong which worked well until some stray "hidden" file got transferred to it. In order to remove the file, which I couldn't access, I reformatted the disc, but the only option was to format it to 244 MG, less than 1/4 of the capacity. Norton System shows it still has the 1 G memory but I can't access it. How can I reformat it to regain the full 1G? Help!! and thanks
