Hi, Stephen,

Thanks for the answer. I added a line as you suggested to my fstab, using
sdb1 (after checking with dmesg for where the thing was connected). I had
to create /media/usbdisk myself with mkdir, and after that I can
mount/umount from the command line.

I think the point to udev is for the computer to automagically recogize my
usb drives, create that mount point, and assign them to the proper mount
point. From what I remember of the introduction to the manual, this should
resolve the kind of issue you were facing with your usb cdrecorder
sometimes being scd0 and sometimes scd1. I don't know if udev modifies
fstab or if we are supposed to do that ourselves.
