Q: Another Win7 Bootcamp failure with Yosemite upgrade (missing 34 GB)
I've been reading what others have been doing per Loner T's instructions, but I'm a bit unclear on the ultimate goal, particularly when using testdisk and looking for "familiar files." I'm hoping for some instructions on how to recover my Win7 partition. I'm running a testdisk deeper search, but again I'm not sure what I'm looking for in that program or if I've followed the correct selections. Here are the outputs from the 4 commands that Loner T has said to provide...
Huge thanks in advance for any help.
MacBook Pro with Retina display, OS X Yosemite (10.10)

Yosemite is corrupting your Bootcamp volume. Notice the gap between GPT#3 and GPT#4.
Using Testdisk, there are two goals, use Quick Search to find NTFS headers, which is usually onto very successful, but Deeper Search shows "missing" NTFS headers. One of these headers has your pre-Yosemite NTFS partition, which needs to be resuscitated. In most cases, it is sitting between GPT#3 and #4, the "missing" 34GB, in your case.
Please use this thread - Yosemite Upgrade Broke Bootcamp as an example of Testdisk and Gdisk usage.
If you are unclear, please post back on this thread, and I will do my best to assist.
