Hi Al, I didn't see that website. An interesting overview. On the label is DYBIT, so that is the pattern obviously. I don't have any RL01/RL02 related stuff, so no experience whatsoever with these drives.
The only thing I knew is that RL0x packs are useless after a bulk erase because of wiping the servo tracks.
Now I wonder where this alignment pack was used for... Like Mattis says, there are more 5440 style drives...
