What is E007?

I have a sharp camcorder viewcamZ VL-Z5. For the last few months it has been reading E007 and won't let me record of playback. Everything else works just fine on the camcorder. I don't know what else to do. I thought leaving it off for a while or even using a different brand of miniDVR would work but that has not solved my problem. What is E007 and how do i fix the problem.
