brent, the eMMC chip in theory is what controls your Internal Data Partition. Anything to do with writing (and ultimately accessing) data from your internal partition is going to involve this chip. This is a BGA Ic and as such you would have to do a reball to replace it. Pretty difficult task for the normal DIY'er. take a look [https://www.youtube.com/watch?v=97nxZwHG5bA|on here] for an idea of what it entails. Hope this helps, good luck.
