Root [MetroPCS/CDMA] SD Card only shows 3.5GB help

[exitprogram]

I partitioned my 16gb SD card to flash a nook to android. It partition my card to be bootable and partitioned it to the size of the image that I had to use.

Since then my card only shows 3.5GB. Ive used mini tool partition wizard to repartition/format as recommended and still shows a little less than 16gb which is normal. Windows explorer shows the same. Only my phone shows the incorrect amount of free space.

I am using the AOKP 4.1Rom with the 2.1 kernel.

Any ideas? I was using Black Bean 4.2 before this with the exact same issue.
