G-RAID 20TB-M1 MacBook Pro: test integrity and update firmware?

Hi,

I have a thunderbolt 2 G-RAID 20TB Drive configured as Raid 1 to mirror my photograph library. After multiple hard disk failures on other drives (edit for clarity other manufacturers, not my G-RAID), I’m about to invest in a new thunderbolt 3 version.
I want to check the status of my current drive (about 4-5 yrs old) and having spoken to my supplier I downloaded the G-RAID with Thunderbolt Configurator.

However when I run the app, it doesn’t give me an option to check configuration, or update firmware, just ‘Configure’. I don’t want to do that until I’ve backed up onto my new drive as I’m worried that configuring the drive may also erase the data.

I can see a big green tick, which I presume is telling me both disks are healthy. Is there any other utility I can run to check disk integrity? And, is it possible to check to see if firmware needs updated without pressing configure? (you can see the firmware number in the screenshot).

Thanks!

Joe
