-<a id="note4">[4]</a> - unRAID completely rebuilds parity when adding a new disk that already contains data, and during this process <a href="https://youtu.be/frtauLMO3-c?t=803">the existing data in the array is not protected</a>.
+<a id="note4">[4]</a> - unRAID 7.2 claims that it can add data disks to an existing array, but in reality, what it actually does is create a new array and rebuild the parity from scratch.
+The key difference is that during this process, the data disks already in the array <a href="https://youtu.be/frtauLMO3-c?t=803">are not protected</a>.
 This is a serious flaw, as a full parity rebuild puts considerable stress on all drives. If any disk is near failure, there’s a high risk it could fail during this operation.
-The only safe way to add a new data disk is to pre-clear it first.
