I wouldn't conclude that the drives were 100% OK from that line,  
although they *might* be; I'd conclude that the drives aren't  
implementing this SMART field correctly in their firmware.  Are you  
using the latest version of smartctl-- updates to that can sometimes  
better interpret vendor-specific odditities.
