Hello List, I need to write a backup script, and one of the required actions would be a copy of the backup to an external firewire drive. I would like to make this as easy as possible for the local staff, so i'd like to check whether the drive is attached, if necessary mount it, copy over the backup and unmount it again, so that the local staff can swap the external disks when they're not used. Is there a canonical way to achieve what i want? I played with the idea of simply checking for /dev/da0s1d's existance, but that won't disappear on disconnect, so that would leave the is a possibility that although da0 is in /dev, it might not be connected. Any ideas or RTFM-pointers? Helge
