      I am getting these weird messages from:

      # cat /var/log/messages

      I don't have a "sdb" device mounted.

      Here is my mounts:

      /dev/sda1 on /initrd type jffs2 (rw)
      /dev/sda1 on / type ext3 (rw,noatime)
      /proc on /proc type proc (rw)
      usbdevfs on /proc/bus/usb type usbdevfs (rw)
      /dev/sda1 on /share/flash/data type ext3 (rw,noatime)
      /dev/sda2 on /share/flash/conf type ext3 (rw,noatime)
      /dev/sdc1 on /share/hdd/data/nslu2storage type ext3 (rw,noatime)

      What is this "sdb"??
