How do I set it up so that /dev/sda4 is created (either at boot or when the device is accessed) but the zip drive is not automatically mounted at boot, and my script can happily mount and unmount the drive when needed?</blockquote><div> I don't use zip drives much so I would have to guess on that part, but I do see why your /dev/sda /mnt/pd auto defaults,noauto,users 0 0 /etc/fstab line gives you the ever. It is because the ext2 partition is on /dev/sda4 and not on the /dev/sda </div>So It looks like the usb drive is being detected by hotplug, but a zip disk is similar to floppy in that the computer doesn't know when you put in the disk (unless there is zip software that can detect it and tell it). So, if you are willing to mount it manually than you should be able to use the line (in /etc/fstab): /dev/sda4 /mnt/pd auto defaults,noauto,users 0 0 you will need to mount and unmount manually. I will have to try out a zip disk to see if hotplug handles them automatically or if you need other software. Hope that helps, probably someone else has some experience with zip disks (otherwise let me know if you still have problems and I will play around with a zip disk later.)
