I just upgraded to 6.4.1 and on my main dashboard I'm seeing warnings regarding a couple of drives and their SMART status

 

The warning is UDMA CRC error count: 1 and CRC error count (no UDMA): 1

 

Can anyone explain what these errors mean, whether theyre serious, and what can be done about them?

Starting wth 6.4.1, unRAID now monitors SMART attribute 199 (UDMA CRC errors) for you.  If you get an alert about this right after upgrading, you can just acknowledge it, as the error probably happened in the past.  If you get an alert down the road, it is likely due to a loose SATA cable. Reseat both ends, or replace if needed. (see this)

The count never gets reset to zero. It only ever increments. So acknowledge the error in the context menu in your first screenshot and it will only reappear if the count increases. If it does then you still have a problem.
