bonjour

un petit souci de controleur ide....

apparement tous lmes disques dur sont HS

quelque soit le disque, j'ai ca dans le dmesg:

unable to read partition table
ide: late registration of driver.

hors j'ai testé tous ces diques sur le port ide primaire et tous 
fonctionnait corectement ....
evidement on pourrait penser que le controleur ide secondaire est HS ....

mais pourtant, quand je branche mon lecteur cd ou mon lectuer zip ide
les deux fonctionnenet corretcement

j'ai rien vu de suspect dans la bios, le disque ets corectement detecté ....

quelqu'un aurait peut etre des infos ?
merci

apparement la mandrake 9.2 utilise le devfs ou supprime les fichier du 
dev inutilises
alors j'ai essaye de recreer a la main ces fichiers:
mknod disque2 b 22 0
mknod disque2 b 22 64

de maniere a pouvor faire un fdisk (si comme c'est ecrit c'est la table 
de partition qui est foutue ebn je la recree)
et ben ca n'as pas fonctionner

merci d'avance
