hmm u saying that the phone is comes from the company 11.25 gb first time we had it right ? .but why is that .

Its all mathematical.
Firstly, hardware manufacturers see 1 KiloByte as 1000 Bytes. So they see 16 GB as 16x1000x1000x1000
However software more accurately sees 1 Kilobyte as 1024 Bytes.
So take your 16x1000x1000x1000 then /1024/1024/1024 and you get 14.9 GB or 14.9 GiB as the hardware industry have forced software to show a true GB.
Ok so then you have 2 GB for Android ROM, 1 GB cache and some aside for /boot, /recovery etc... yeah, you're left with 11.25 - 11.35 free space

No probs

I have flashed custom roms 3-4 times and I sincerely feel that when I wipe/factory reset, all the memory has not been wiped. I have attached my storage screenshot on my i9300 (international s3) running in pacman rom jb 4.2.2. It doesn't add up. Where are the remaining memory? Interestingly, when I went BACK to pacman from stock it remembered the wallpaper that I had. What is the use of a wipe then?

how do you wipe? from recovery? that doesn't clean the internal sd.
if you flashed 4.2, your internal sd is now in /data/media/0, and before it was just /data/media.
so your internal sd contents from 4.1.x are still there in /data/media, taking up space

Oh.. Ok, thanks... Now is there any method where I can truly wipe out EVERYTHING and start fresh? Something like right out of factory, but only with custom rom? Btw, thanks for the quick info...

use Megawipe.it will wipe everythimg, so you'll need to flash a rom right after it

Glenbun. Stop trying to get your thanks up. When you ask for it all the time, its desperation. My policy is if they ask. Then they don't get it. Oh well move one.

This did the trick, now I am able to see all 11gb of internal storage. The process was also quite simple. A must do step for every room change.

No. Not every change. Just when you swap between 4.1 and 4.2
