This worked like a boss. Even on a 3TB (GPT MS file table) formatted with ext2 on Windows Server 2008 R2. Fantastic. For those with GPT file tables (if you have a filesystem bigger than 2TB, you will), I did a Google search "TestDisk gpt" and found some git commits (dated ~2010) which corrected a couple of bugs for GPT. The TestDisk version 6.11.3 (6 May 2009) would have this bug, so I used the Beta WIP version, 6.12. I encountered no problems using the Beta.
