I bet the problem you have is the sd card not making contact with the pins, take it out press the middle of the slider inwards so to bow it very slightly then reinsert making sure you get the little tabs under the lips when you push the slider in place.

I had this problem and also seen it on other devices too and it was the sd card itself not making proper contact, try it it will cost you nothing.

Incidently the mesage given was the same as you have, memory card corrupted.
