I can't get the /data partition to recognize as anything other than 4GB. I've used Mega Wipe, flashed a stock 4.3 rom w Odin, wiped data, formatted data, flashed a pit file in Odin. I don't see any backups, Disk Usage only sees the partition as 4GB. I've done this all many times just to make sure.
My mmcblk0 partition says unmounted and is 7.5GB. Could this be my issue?
