Bonjour à tous
 
J'ai un problème d'écrire sur un HD externe USB2 (fat32).
La lecture ne pose aucun problème.
 
Je parviens à écrire mais après un transfert de +/- 50 Mb, la copie s'arrête de nombreuses minutes puis se remet à copier quelques mega...
 
Le disque n'est pas en cause car il marche très bien sur un autre ordi.
 
Je ne vois rien de spécial dans les logs.
 
Quelqu'un à une idée ?
 
CM asus a7n8x
Kernel 2.6.10 (même problème avec le 2.6.9)
 
Merci d'avance pour votre aide.

J'ai été un peu vite en disant qu'il n'y avait rien dans les log

C'est grave docteur ?

si tu as un noyau 2.6.10/2.6.11, tu peux essayer le pilote ub en lieu et place du pilote usb-storage.
 
il est plus lent pour la lecture/écriture mais il est plus stable/robuste.
