OK, That is odd in some ways and ???? in others.

Yours is the first to report a problem with Mirroring. The problem you explained with the shares have never been reported before, at least on this forum. Which may explain why this message "This page is not available because no disks were found." is present. This indicates the system is corupted. I do not recall what OS you are on but, you may need to reinstall it. Then I would changed the 2200 back to JOBD, reformat to clearup any drive corruption, then back again. Then run your test again.

You discovered that only another snap can read the HD's. And depending on model it must be the same model and OS. The 2200 OS resides on the HD, It is the only 2 drive unit with the OS on the HD. So you could not move it to any other model.
