One of my data disks (disk #1) indicates disk read errors, (6 read errors today).  I ran a SMART short self-test which completed successfully, no errors.

 

Disk #1 is relatively new ~ 6 months old.  Syslog is attached.  I can re-seat the disk....haven't done that yet.  Haven't checked cabling either.

 

Is there anything to worry about or any action to take?  Do I ignore for the moment and monitor?  Any risk of data loss?

Did you test the drive with preclear before using it?

 

Instead of posting syslog, for v6 it is better to go to Tools - Diagnostics and post the complete diagnostic zip file.

Yes, I precleared with 3 full cycles.  I've attached the diagnostics zip file.

Don't see anything obvious. SMART looks good. Maybe check connections as you said.

Thanks.  Will check connections and re-seat drive, then monitor.
