The drives iam trying to add are all new even run a s.m.a.r.t. extended test without any issues. and pre-clear also. But when adding to array i noticed this.   Even done a clean unraid install since kinda touth it was a issue there. but that wasnt it.  

 

What i have done so far:

Changed out the cables "sas mini to sata"

Changed out the sas controllers

Clean install off Unraid as stated above.

 

i have also replaced the cables "sas mini to sata" and the sas controllers.   

 

MB: Asus ROG STRIX B450-F GAMING

PSU:  Evga 650W GS2

Controllers: LSI 9210-8I in IT MODE

Atm i only have 4 drives connected  and 2 nvme``s. 

 

Anyone got any idea or tips on what can be the issue?  

 

PS: i do have the logs/diagnostic from before i did a clean unraid if thats wanted also.

Those are normal for new array drives, just ignore, once they are added and formatted the errors will be gone.
