[Xymon] usb disk not showing

[Kris Springer]

I've recently installed a xymon server on Debian to monitor my home 
network, and I'd like the server to also show the status of a USB drive 
I have plugged into it.  The drive is listed as /dev/sda and mounted at 
/media/user/USB-1TB
It is listed in the xymon client data, but it doesn't show up on the 
'disk' or 'inode' columns at all.  I've commented out the default IGNORE 
rules from analysis.cfg and even tried adding the following as a host 
specific test, but still nothing appears.
DISK /dev/sda 80 90
INODE /dev/sda 80 90

Anyone have a clue they could give me?
