Another thing is that this feature has to be configured per USB device. You have to enable it in sysfs for your specific harddisk. Also remember to stick the disk into the same USB port where it came from, as this feature will declare your mounted USB device dead when it isn't found on the same port. _______________________________________________ arch mailing list arch@archlinux.org http://archlinux.org/mailman/listinfo/arch
