Thanks for that. I didn't actually want to use hotplugd if I could help it as I was trying for a different approach. I was hoping to use physical lables on the USB disks with labelled USB cables but I've just found out during testing that the connection between a USB device and a physical cable is not as simple as I first thought. I unplugged all the disks and plugged one back into a labelled port. That port used to be /dev/usb4 "addr 5". but it seems it's now /dev/usb4 "addr 3" and "addr 5" doesn't seem to exist anymore. Looks like I'm going to have to use disklabel to label each disk and hotplug to mount them. The backup script will have to check the mount point to make sure the disk is mounted and unmount it after the backup is finished. In other words, the script I posted earlier is useless folks.. My problem now is to figure out how to get our people to work with this. Preparing a new USB disk is not going to be easy for them. I'm probably going to have to write a web interface for it <sigh>. Thanks for the help everyone! ciao dave --- Dave Edwards
