I was attempting to expand a 320GB & 1TB native to 4TB. With the help of jmbach, I wanted to share the new iso I built with a patched JMFS and a collection of tools from different individuals. This should help streamline jmbach's process he outlined. The current limitation of JMFS only allows a maximum partition size of 2.2TB due to 32bit tables. This patch allows you to expand beyond 1.5TB which otherwise isn't possible with rev104. The iso I built is based off the source in krbaker's github and the AppleDisk patch. krbaker's source will clean up Apple_Free partitions if they exist when doing a JMFS copy. Lastly I included some TivoTools scripts written by TCF member marwatk from this post. In the following posts, I'll explain my process and how I built the new iso.
