I just purchased a "used" Samsung SSD for use on my Dell R820. When I plug it in, the server sees it, Preclear states "Cannot Preclear". The logs show this:

Unraid is showing this:

I stopped the array, and still no joy. Did I happen to get a bad drive, or is there a way to "wipe" the drive and make Unraid look at it again?
