Bon courage !! Et merci pour le temps que tu consacre à mon problème !

Bonsoir,

Trouvé ... Ne vous cassez plus la tête à tous lire, j'ai les infos pour comprendre et expliquer ce qu'il se passe ...

Juste le te de le rédiger, et la réponse sera là.

à desuite ...

Voilà ...

Ce qu'il se passe est assez simple, le disque IDE ne se "démonte" car, j'ai l'impression, qu'il "n’avertis" pas le kernel de sa "disparition" ...
Cela peut paraître dingue, mais c'est en "gros" ce qu'il se passe ...
Ha oui, petit détail ... je ne pense pas que ce soit le Disque IDE qui pose problème, mais le convertisseur IDE -> USB.
Oui, je pense cela car, si je ne dis pas de bêtise, ce module a un certain age : Avec cette information, je suis tombé sur un article de 2007 ... je suis sur qu'en cherchant un peu, on peut trouver plus vieux.

Dans les détails :
Lors du premier exercice, tu as démarré ton RPI avec tes 2 disques.
Ici on voit la présence de tes 2 disques :
Via fdisk -l : via le mount : On voit les informations de ton disque via dmesg ou dans le /var/log/syslog : dans le /var/log/syslog, on remarque que la partition sdb1 est montée, mais pas la sda1, étrange mais bon, on sait qu'elle est montée, ... étrange ... Lors du second exercice, tu as coupé tes disques.
Dans le /var/log/syslog, on y trouve la mention ou le system signale la disparition des 2 adaptateurs USB et qu'il a démonté automatiquement la partition sdb1, toujours aucune trace de sda1 ... étrange ... Cependant, mount signale que le disque sda1 est toujours monté ... étrange ... Là ou cela devient intéressant, c'est durant le troisième exercice ou tu rallumes tes disques.

On repère bien tes 2 disques, mais le sda s'est transformé en sdc :
On le voit via fdisk -l : On le voit également via dmesg : Mais le sda1 est toujours monté, selon la commande mount, sdb1 est de nouveau monté correctement : Conclusion, ton RPI n’apprécie pas le montage et le démontage à chaud de ton disque IDE.
Pour palier à cela, tu as trois solutions qui s'offrent à toi :

• Soit tu achètes un nouveau disque sata et ton adaptateur USB.
• Soit tu achètes un nouvel adaptateur IDE -> USB.
• Soit tu élimines ton disque IDE.

Aussi, et pour finir, si tu n'utilises tes disques que sur ton RPI, je te conseil de les formater en EXT3 ou EXT4.
Le NTFS à tendance à bouffer beaucoup de ressources du RPI.
Voir le sujet : viewtopic.php?f=3&t=515&hilit=ntfs

Voila, j'espère avoir répondu à tes questions.

Bonne soirée,

Woua! merci pour ta réponse détaillée, j'ai tous compris ! Et au passage j'ai appris quelques commandes.
L'interface est toutes neuves, mais c'est la moins chère de ldlc...donc probablement un vieux modèle.
Tant pis pour moi j'aurais du vérifier avant sa "compatibilité".

Il n'y a pas une commande qui peux envoyer l'info au kernel que le disque est démonté? umount ne permet pas cela ?
Sinon je prendrais une nouvelle interface IDE-USB en me renseignant mieux pour la choisir. J'ai pas mal de disque IDE d'un ancien PC, ça me permet de les réutiliser.

OK je ne savais pas que le NTFS avait cette effet sur le RASP. Je vais les formater en ext alors.

Merci encore pour ton aide !

Bon j'ai testé pour le umount.
Ça fonctionne pour démonter.
Mais si j'éteint/rallume le disque à chaud : le mount ne passera pas.

Bonsoir,

Le NTFS n'est visiblement pas fermé correctement,
ou alors, autre solution,
le NTFS pose quelques problèmes et il serait peu être temps de le brancher sur un Windows pour faire un "check file system" avant de continuer sous Linux.

Bonne soirée,

EDIT : Mais si tu format tes disques en EXT3 ou EXT4, tu ne devrais plus avoir de problème avec le NTFS ... logique implacable.
/!\ ATTENTION : Un formatage nuit gravement à la santé de vos données !
