DiskUtility shows two HD

[maggarjt]

My friend has a macbook pro and with yosemite the computer is ultra slow and tons of beach ball. I looked in disk utility and it shows two Macintosh HD. Here is the output from the terminal. Any help would be appreciated. I am trying to make this thing run correct again. I am willing to get a new HD and clone but if I can fix without going through the trouble I would like to.

Thanks so much

Totally normal and there is nothing wrong there. On some newer Mac laptops Yosemite converts the drive into what is called a "core storage" logical volume and that is what you are seeing.

If you are getting beachballs etc, it is not from this.

What do you get if you run disk first aid there in Disk Utility. It almost sounds like a failing drive from what you describe.
