Hashcat and Sandisk Secure Access

Well, I finally got oclHashcat (cuda) running on Kali-linux. I am using the Nvidia GTX-750ti. I have been messing with dictionary attacks, combinations and mostly mask attacks. Some time ago I encrypted a Sandisk 32 Gb drive. Not only did I encrypt it with a password, I did it after I had taken my Ambien. Needless to say, I might as well have had my neighbor come over and put in a password because I have no idea what it is. The one thing I am confused about is salts. I understand what they are, websites use them all the time because a lot of people use simple passwords. When I was digging around in the Sandiskdrive, I found two hashes. I put them into the Hash-Id and they are SHA-512's. I am confused because I thought a salt was a simple phrase that was then combined with your password giving you one hash? I've included a pic. The hashes are
"6401c89f3971af3fd2819e574ac2576b40a601e0b01863153162cc0db6ddfe15"

If anyone could point me in the right direction, I would be so grateful.
Thanks
