Error Running Datalogger Tutorial

I formatted my sd and created a "arduino" folder in the root directory.

When I run the Datalogger tutorial sketch, I keep getting:

"error opening datalog.txt"

Why is this happening? I also tried to create a file in the arduino root folder and run

(FileSystem.exists("/mnt/sd/") == true)

but it only returns false. The SD card looks like it can't be pushed any further into the socket. I don't know what else to try/do.

Any leads would be helpful!
