Vérifier les "Autorisations du disque"

Hello,

Sans vraiment de raison, j'ai "vérifié les autorisations" du HD de mon
Mac (iMac G5, 10.3.8). L'utilitaire de disque m'a renvoyé le message
ci-dessous. Rien dans la doc ne me permet de l'interpréter. Que dois-je
faire ? Réparer ? Retourner me coucher ? Pleurer en appelant maman ?

Merci de vos conseils

Alfred
