CWM external SD card unable to mount

I was having no problems using and accessing my external sd card from within CWM. Than after some flashes and wipes trying out different roms, and even a complete reset to original rom through ODIN to try and fix it. I can no longer use my external sd card in CWM. It says something along the lines of E:/ cannot mount external sd. Does anyone know what could be causing this, and if there are any solutions?
