forgot to mention, I'm also running the AD add-on.
based on other posts, I've checked and it does say something about sync'ing - for whatever reason...
Sync Time Remaining: 822.3 minute(s)
I haven't changed anything on the drives or had one fail (or gotten an email alert).
I guess that might be from hard booting it....
anyways, I'm going to wait until that finishes to re-update the FW.
