Default [Q] cannot mount inner sd card on coby kyros mid 9742

hi i have a coby kyros mid9742 and i am a bit of a noob so here goes, please be gentle.
i am having a problem with my sd card after i rooted my tablet. i rooted,dumped image, flashed cwm then flashed mobiz v2. everything works even g/play but for some reason i cannot mount the internal sd card so the camera works but wont take pictures and it tells me that there is no sd card present.
i think i have tried most things so any suggetions would be great
i was going to restore the original image but i couldnt figure out how to do it. thx.
