Partitioned HD Lost With Update

[jr17c]

Hi All,
Sorry I'm the guy who creates an account to ask a question, but I'm the guy who created an account to ask a question.

I updated to Yosemite from Lion. I had a partitioned HD that I used to keep super secret stuff on. When I updated, the drive is no longer there. Any ideas on how to recover it?

Run each of the commands below in Terminal and post the output of each command here so I can see how your partitions are setup. Yosemite converts come drives to core storage volumes and that makes the partitions look different.
