Good question.  The RFC is not very explicit on this issue.  For
Sequent's implementation, I chose to make the hrDeviceStatus of a device
with removable media be 'down(5)' when no media is installed.  This
doesn't feel great but I personally liked it better than 'unknown(1)'.
When hostmib is revised, I hope this area will be clarified.

I return 0 for hrDiskStorageCapacity when there is no media in the
device.  I think zero accurately describes the capacity of the device at
that time.
