Thank you for contacting Intel Customer Support.
We recommend testing different sata cable. Can you also please let us know if you are using a backplane in order to connect the hard drives?
We will look forward for your response
Yes I am using an Intel HDD Cage 8 X 3.5. It has two drive bays (4 drives per bay), Each bay has its own I2C cable. I am only using one of the bays as I only have 4 drives. I swapped the cables and the problem, went away. I waited a few days before responding to make sure it was fixed. I will replace the bad cable if I decide to add additional drives in the future.
Thanks for your help.
