Sorry i know my following question have been ask alot of times already.

I just brought a 512MB rs-mmc card, same problem using nokia 6260 to format, everytime it just hang, then when restart phone it prompts memory card corrupted.

but then i could use a card reader to format it to FAT. But the previous 32MB card when ever i slot it in the Card Reader, i cannot see the detail inside. It will prompt me to format it. Y is it so.

Please Advice.
