One of our drives has a yellow square overlay on its icon in the Drives list. I think there's an "r" in the square (see image). I can't find this described in the MegaRAID manual anywhere.
When I view drive properties while flipping back and forth between this drive and the others, the only difference I notice is that this one has "Full Disk Encryption capable: yes" whereas the others are "no".
Anyone know what this means?
