Hi folks,

 

still learning how to manage UnRaid as I move towards the end of my trial period and so far I received 4 CRC errors on one of my disks. Today the 4th error has been reported and I am curious whether I should worry. The disks are brand new, all of the same type. Its my main disk where these erros occur.

From the logs below I understand tha there is something going wrong with the disk bus system. I am using WD Red 4TB NAS disks.

 

Any advise? So far I am acknowledging the errors only. I also checked the Sata cables.

Would ECC Memory do any trick here?

First thing to do is to replace the SATA cable

CRC errors are very rarely a drive problem as they indicate a connection issue.

Thanks guys, I swapped the Sata cable and will monitor this further on.
