[périphériques USB]passage intempestif en mode ro

[jeune personne]

bonjour,

j'ai deux périphériques USB formatés en fat32 qui me posent le problème suivant :
lorsque je les branche, je peux lire et écrire dessus, mais rapidement, les périphériques passent en mode read only. je repasse en mode rw en débranchant et rebranchant les prises USB.
la commmande cat /etc/mtab montre que les périphériques sont montés avec l'option errors=remount-ro
que faire ?
merci d'avance

[Elbarto]

je pense qu'il faudrait avant tout vérifier si les partitions fat32 de ces périphériques USB ne comportent pas d'erreurs,

il y a pour cela l'utilitaire dosfsck du paquet dosfstools :

http://doc.ubuntu-fr.org/dosfsck

une fois les partitions fat32 réparées ce problème du passage en mode read only devrait prendre fin

[jeune personne]

merci d'avoir répondu si rapidement. je vais essayer ça et voir si ça fonctionne.
bonne soirée

[jeune personne]

voilà ce que me répond le terminal. Pouvez vous m'expliquer ce que ça signifie ?

Il serait plus sage de vérifier des clés fat32 sur un Windows.
