uhmm i just bought a 1 gig micro sd for my cell to put songs and stuff. However... when I add too many songs, it says "the directory or file cannot be created". I check how much space is left and i only used about 400 mb of the 1 gig thats still in there. When i look at the capacity, it looks as if I can only use 50% of the memory. i deleted a song and added another one and it worked, as if I can't put in a certain amount of memory exceeding a limit. But, i'm not even near 1 gb yet, i've only used 485 mb so far out of the 1 G the micro sd comes with. Can anyone help me PLEASE!?
