Possibly ... that tends to indicate the enclosure data returned stopped
in the middle of the actual specification ... although looking at the
output this doesn't seem to be the case. The zeros at the end
definitely indicate we have enough data, just that the expected
termination doesn't seem to be present.

This may also be a problem. My enclosure returns page 7 as well. The
traversal routine has special code to try to parse page 10 without a
page 7 ... I don't think I actually ever tested that ...
