Sandisk iXspand lost capacity

i got ixspand and my brother formatted it and it only has 30.6 mb can you guys help me with my problem

the ixpand uses a micro sd card inside of it. you can try formatting with the SD formatter linked below. If that does not fix it it would need to be replaced. in that case contact sandisk support to check warranty status.
