Writing to SD Card Error?

Hi, I’m not sure if anyone else seems to be having a problem like this?
I have an Elegiant 8GB Class 10HC microSD that I am trying to write the image for RasPlex on.
And write away I get two errors (see picture).

Is anyone familiar with this error/a solution for it?

Haha… I feel stupid…
My SD Card adaptor was apparently 1/2 way in the “Locked” position… 'doh!

… so… Solved.
