Another issue to tackle - I have an external 1 TB drive (2 500GB on a RAID). 
When I plug it into the server, it sees, via /var/log/messages, that a USB 
device was plugged in, but that's it.   fdisk -l doesn't see it.  dmesg doesn't 
do much, either.   It is a Western Digital My Book II device.

I want to format it and use it for external storage, but can't until I get to 
it.    What is the best way to get to the drive?
