Hi all

 

Yesterday I got an email from my NAS about read errors after 5 tries.

I rebooted system and did a quick SMART test on both disks, no error reported.

 

Today, same problem and I took a look in /var/log/messages via ssh

No more doubt disk1 has defect sectors.

I shutdowned NAS, remove disk 1 and NAS restarted from disk 2 in degradated mode.

 

Question :

 

- Why did SMART didn't reports any errors before this failure ?

- SMART on WD Green is safe ?

- Do you thing Data Lifeguard Diagnostic for Windows will be able to fix bad sectors and remap them or should I send disk to repair ?

 

Thanks for your help
