re suselinux 10

hi and happy new year, after installing 10 I ran the automatic repair and: filesystem postfix showed up in need of repair and have consistently shown themselves to need repair whenever repair is run? Anybody know why? Can anybody tell me how to delete extra cd/dvd units which were changed. the machine recognizes the new one but I cannot remove the old ones which are no longer on the machine? Otherwise 10 runs smoothly best -- Cheers, Serge
