I've been just ignoring them, but as I get other things worked out that 
bubbles toward the top of the list.   
 
It throws about six errors on startup, then says it's disabling DMA for that 
disk.  Given the vintage, I wouldn't be surprised if it isn't DMA capable.

Looks like I have plenty of opportunity to learn about HD tuning...
