Help Updated to 4.4 but lost half my storage

I have a identical problem, after upgrading to kitkat using kies for my samsung note 10.1 2012, the internal storage is now displayed 16 gb instead of 32gb.
I searched a lot and arrive to this post. I don't know how to lock and unlock the bootloader in samsung note 10.1. 1.
Anyone please help me.

Welcome to Android Forums :)

I've moved your post (originally a reply to an old thread in the Nexus 7 forum) to a new thread in the forum dedicated to your device. I can't answer your question but hopefully other Samsung Note 10.1 users will have an answer :)
