Unhappy [Q] sd ext mount

Hello everybody
Yes I finally decided to install a lighter and faster rom for my Galaxy Note n7000 (Asylum Kitkat 4.4)...but something went wrong, therfore my 16gb ext sd is not seen by the system. Es explorer is able to see it.
I used to have the apps moved to sd with Link2SD
I am a complete newby to this so, please, help me...
