I had this problem recently. What you should do is download an app called 'dummy file generator'
you can download it here or via play store
dummy file
if your phone keeps freezing that makes you not be able to have downloading process, try download the .apk file. find it on google.com search 'dummy file generator .apk' and send it to the phone and install it.

next step if your dummy file generator installed:
*open it
*Just tap on the generate (full)
*it will process your phone for  a while
*and delete f*cking dummy files
*a single process above is used for 8 GB
*S3 has 16 GB memory
*so do the process above twice
*enjoy like a boss!!

How to format and install your new HD also with the OS X.
First i assume you have replaced your HD.
1 thing that we know you don't have anything inside the new HD, so If you have OS X disk, you can use it.

But if you lose your disk or you don't get or you have trouble with disk player
(only for OS X lion and OS X mountain lion, for the older version please download 'Internet Recovery System' on apple support.)
*turn on and press command and R
*no apple logo
*it says it needs internet
*find wifi or ethernet
