I have a OWC Mercury Pro Elite Qx2. I have 4 4TB Hitachi drives setup on a RAID 5.
One day, the red light came on indicating that my C drive has failed. I took it out, and put it on my docking station. Ran some diagnostics using OSX Disk Utility and SMART Utility. Reformatted the drive, the drive passed both the verification and the repair.
When I stuck it back in the OWC box, the "rebuilding array" light came on, a minute later it gave me the same red light indicating a failure. I am not sure why it is saying the drive is faulty. I have tested this drive pretty thoroughly outside of the RAID set and it seems fine.
All four drives are of the same model & firmware. They were bought at the same time, so its probable they came in the same batch.
Any thoughts on why this is happening? I am hesitant to purchase a new 4TB drive just to have the RAID go funky with putting in another drive of a different firmware/model.
Any help is appreciated.
