Volume completed validation.  I repeated instructions in your previous post.  I did not re-validate the volume.  Next, I initialized the new drive, and then added to the RAID5 volume.  As of this writing, the volume is rebuilding and all is acting normally.

Thank you for your help.

One validation will be enough, to make sure the parity data is updated. You will see in the volume tile a date "last validated"

With respect to the General Tab.  There is a message that states "Some system software requires your attention before it can be used."  When  I select Details I see "Other World Computing".  The box is not checked.  I will check that box.

The volume has mounted and I have begun validation.

I do not know how to stop the validation process.  But once validation is complete, I will start the process again that you outlined above.

I actually meant the general pane, and there should have been a pop up dialog box directing you there. Otherwise, macOS will block the driver from loading.

In System Preferences/Security the first tab (general) should be the open tab, and "Allow" would normally be there.

I recommend users wait until the macOS dialog box pops up, as if you install the driver and restart immediately, you may miss this option, then you have a limited time to do that. In Monterey, I am pretty sure the pop up will repeat at restart, reminding users to Allow the installed driver to be loadable.

Is your volume mounted currently?

Ok.  I have uninstalled the driver and re-booted.  I got an error message about the drive stating that the "Disk you attached was not readable...."  I selected ignore.

Next, I launched SoftRAID and got a message Install Drive.  I selected Install.  I received a message that driver was successfully installed.  So I am assuming at this point I am not to install the driver again from the utilities menu.

Then you requested the I " "Allow" OWC at System Preferences/Security".  With this I am assuming that I need to go Privacy.  Is this correct?  If yes, there is no selection to Allow OWC.  Did you mean Select "Full Disk Access" and select SoftRAID 6.2.  I made this selection.

I then re-booted and launched SoftRAID.  Got two messages: 1) Array was missing disks and 2) Driver successfully installed.

Currently, validating the Volume and will take about 6 hours.

Please let me know if the above is correct because I have made several assumptions about items that were not in your directions.

Driver is enough in this case.

When you state "uninstall SoftRAID" do you want me to "Uninstall SoftRAID Driver" or "Uninstall All SoftRAID Components"

Don

Use this:

"uninstall SoftRAID" utilities menu

restart.

Run SoftRAID and install the driver

Before restarting, "Allow" OWC at System Preferences/Security.

Now restart.

Now "validate" your volume. This is important because of what happened.

let me know.
