Bonjour,
Je suis sur Wheezy avec le noyau 3.2.0-4-686-pae
Je viens de mettre en place une carte PCI StarTech avec un chipset VT6421 pour pouvoir brancher un boîtier DDur externe en e-SATA et faire des sauvegardes complètes de mon disque.
La carte a une prise SATA à l’intérieur et une prise e-SATA à l’extérieur.
Caractéristiques ici : http://fr.startech.com/Cartes-Additionelles-et-Peripheriques/Controleurs-HDD/SATA/Carte-controleur-1-port-eSATA-1-port-SATA-PCI-SATA-avec-support-faible-encombrement~PCIESATA2I
La carte est bien reconnue. Résultat du lspci :
Mon problème est celui-ci :
- Si je boote mon serveur et que le boîtier est déjà branché, tout fonctionne à merveille, mon disque externe branché en e-SATA est bien visible quand je fais fdisk -l
- Si je débranche mon disque, le noyau n’est pas content du tout (cf plus bas), et si je le branche il ne se passe plus rien (rien avec fdisk -l)
- Si je boote mon serveur et que le boîtier n’est pas branché mais que je le branche plus tard, mon disque n’est pas reconnu (rien avec fdisk -l).
Du coup je suis bien embêté, car je n’ai pas envie de redémarrer mon serveur chaque fois que je veux faire une sauvegarde… 
Rapport du boot avec le disque branché (le boîtier externe correspond à ata4, on le retrouve ensuite sur /dev/sdc ) :

Y a-t-il une solution à mon problème ? J’imagine que oui, puisque le principe des disques SATA est de pouvoir les monter à chaud, non ?
