ty i get the mmc2 card worknig now i erase the partition using a partition software because windows disk manager dont let me because its says that the disk operations like erase can't be donde in removable disks.
so i erase the partition and format with the software but didnt work like i said but then i just erase the partition again with the partition software and create the new partition using windos disk mananager and it work fine :P i think that the paritition software do something wrong creating parititons
