You certainly called the SMART issue, I was wondering why a new 
distribution install on some older hardware was getting all the errors, 
clearly the Fedora "smartd" doesn't check SMART capability before trying 
to enable the feature. Oddly the drive on which I see this does reply to 
SMART requests, so the firmware must be "semi-functional." Not a 
problem, in my case the drive is just used for testing handling of hot 
swap, and has no data of any value.
