So I figured out what works for me. Downloading that Zatta app didn't work for me, probably because I'm not rooted.
Okay so go to Settings>More>USB Utilities>Connect Storage to PC
If you're charging through USB it will tell you, "USB is connected. Remove the cable." So remove it and plug it back in again and then click the button which now says, "Turn on USB storage" then OK.
Now it should be using it like a disk drive.
Hopefully this works for you. I just switched from my HTC so everything is messy. In other words I have now my old folder that I named when the SD card was in my HTC and another drive, "Removable Disk" under that. But all my new and current files are there.
