Re : disque dur externe invisbile !

oui , combien as-tu d'usb ? et sur le nombre total, combien sont branches ?

le dd externe a un seul connecteur usb ? pas deux via un connecteur Y ? si oui essaie l'autre branche... sinon essaie d'y connecter une alim supplementaire...

Re : disque dur externe invisbile !

1.deux en façade : pris par mon DDExt 2,5" pour lancer LinuxMint ou Ubuntu en Live
2. plusieurs en arrière où est branché mon DDExt. 3,5" avec alim externe pour l'alimenter et un connecteur/convertisseur SATA/USB
