My twinmos 256mb dv rsmmc worked fine in my nokia6630. I just bought a 512mb kingston. phone find it. formats it. but when I wanna copy my old files to the new mmc it gives error on certain files. like the ones with more then 3 letter in extentions. Im guessing this is caused by the fact that the filesystem isnt Fat16. anyone know how I can format the mmc without a cardreader?? like using a app on pc or soemthing?
