Drive SMART Errors

Hi all,

I have 4x WDC WD2002FAEX drives (identical) in a Netgear ReadyNAS Ultra 4 PLUS. I just got a warning at a reboot today that a couple disks have some SMART reported errors.

Are these things I could get the drives RMA'd for? Or do I have to wade through it until they really fail? Will Western Digital RMA drives with these SMART error reports or will I need to backup the data and then run their tool?

I absolutely cannot lose data on this RAID, so I guess it's time to backup the backup.

Here's what I see:
