Hard drive failure

So, one of the hard drives failed in our WD Sentinel DX4000 8TB device (4 - 2TB drives). WD sends me a replacement drive since the unit is still under warranty. The drive is a 3TB drive; I am told by WD that the 2TB drives are no longer available.
Can I put a 3TB drive in this unit to replace the 2 TB drive. What needs to be done to get this drive “working” with the other drives?

Just stick it in and it should replace the other one (automatic rebuild) You will just have 1tb of unusable wasted space

What if Automatic Rebuild is disabled? :grinning:

You should not have any say so in the rebuild unless you have added the Intel Raid stuff which probably broke more than it helped.
