[Ubuntu] pb de montage d'un disque dur usb externe (sda: assuming drive cache: write through)

Bonjour.

Ce disque dur externe (Lacie, USB 2.0) fonctionnait tr=E8s bien avec la
version 4.10 d'Ubuntu.
Depuis la 5.04, il n'est plus utilisable.

Sympt=F4mes :
- d=E8s l'installation (pendant l'installation), le message "sda:
assuming drive cache: write through" envahit la console environ une
fois par seconde. Il apparait =E9galement d=E8s que le disque externe est
allum=E9.
- disque dur externe non reconnu, ne monte pas
- programme syst=E8me>administration>gestionnaire de p=E9riph=E9riques se
plante d=E8s le lancement
- l'occupation cpu passe =E0 100% au m=EAme rythme que les messages sur
la console, ce qui rend le syst=E8me tr=E8s peu r=E9actif
- tous les sympt=F4mes disparaissent si j'=E9teins le dd (mais comme
toutes les donn=E9es sont dessus...)

Quelques recherches sur google me laissent penser qu'il s'agit d'un
probl=E8me de pilote, mais je n'en ai pas compris plus.

La lecture d'un post m'a fait rajouter uhci-hcd =E0 la fin de
/etc/modules, sans grand succ=E8s : les sympt=F4mes disparaissent, mais
le disque n'est toujours pas mont=E9 ni reconnu (j'ai supprim=E9 ohci-hcd
par la commande rmmod, sinon les sympt=F4mes persistent). Mais en
touchant aux modules, je joue clairement =E0 l'apprenti sorcier : cela
d=E9passe de loin mes connaissances.

C'est =E0 peu pr=E8s tout, n'h=E9sitez pas =E0 me poser des questions.
