Was hoping to get a hand with an error I'm continously seeing.  I added a WDC DS520 to my server.  I am receiving the following error.  Steps I've taken to troubleshoot:

 

1. Remove WDC drive from the array (Error Stays)

2. Recable WDC drive along with replace cables (Error Stays)

3. Recable all SATA and Power Connecctors  (No Joy)

 

Diags are attached.  Thanks for the help in advancee.

Not an option.  I will buy an IT Mode HBA if I fail to find an alternative path.

I do and will remove it after a parity resync.  I'm becoming careless with the data and need to make sure it's properly protected.  

 

Why the concern with powertop?

depending on the used version and your hardware, it might seriously kill your sata connections now and then.

It programs the SATA port to "auto" power saving which does not really work reliable on many controllers. Symptoms are loss of contact, unstable data transmission, degregation in link speed (like you are currently suffering from).

It saves little, but can cause a lot of grief.

Thanks you...you were spot on.
