1. The controller couldn't care less about make / model. There is NOTHING in the firmware that looks at that. If a disk isn't supported, it is going to be for other reasons.
You replaced a WD RE4 (RAID Edition) with a WD Black.
I purchased a new 500GB Western Digital hard drive model WD5003AZLX and used it to replace a failing WD5003ABYX 500GB HD. The system recognized it as an SSD and it was unusable in the RAID system.
I purchased a new 500GB Western Digital hard drive model WD5003ABYX with the model number matching what was being replaced. This worked.
I realize that this is empirical data and only a single data point. Yet, that's what happened.
Perhaps it would be good for others to know why? I sure don't.
