@shutt1e PMed me and asked me to dump the first 1 MB of my mmcblk0 ( this references the entire partition btw ;) ). Anyway as per my previous post he asked me to dump with this 'dd' command-line -- 'dd if=/dev/block/mmcblk0 of=/storage/external_SD/out.img bs=512 count=2048'. I did exactly that. Then uploaded for him to view, tomorrow I'd say.

I decided to have a look at what I had dumped. I opened the dump in IDA, using Hex-View btw, and started scanning thru the dump. Well after a minute or two I noticed a pattern. Starting at offset 0x400 ( 1024 ) in increments of 0x80 ( 128 ), all the way up to 0xA80 ( 2688 ), I noticed a common signature. The same 16 bytes starts each of these sections. 44 bytes plus the previous 16 bytes in to these sections is where a partition name starts and appears to be allotted the remainder of the 128 bytes ( 128 - 60 = 68 ). There are exactly 14 of these similar entries. We have 14 different mmcblk0pXX partitions. Anyone else seeing what I think I'm seeing... PIT information possibly ???

Anyone else interested in taking a look may do so. Possibly post any findings. I'm not asking everyone or anyone to download IDA. Any hex editor will do. That's all I'm using IDA for anyway.

Dump is attached to the bottom of this post. Can also be downloaded here

Little preview showing the first 3 sections of this "Table" that I think I've found.
