Full disclosure:  noob right here.

I’ve a desktop constructed on a Gigabyte B460 Aorus Professional AC MB.

The system has a RAID 1 array for the OS and people drives have to be changed as they’re too small.

I need to use the Intel Speedy Storage Know-how app to rebuild the drive, however I can’t set up the IRST utility.

1.  I imagine the BIOS setup is right:  operating in SATA Mode

2.  The IRST app is just not current within the App menu.

3.  BIOS reveals the Intel RAID driver put in:

3.  System Supervisor doesn’t present IRST put in:

4.  I’ve tried to load the IRST Driver 18.7.0.1002.  The .exe file begins operating, then a window with (I assume) a digital drive F: seems, then it disappears, then the dialog window states set up is full.  The app does NOT seem after rebooting.

5.  This is a shot of my Intel storage display screen dashboard.

Any ideas on putting in the IRST utility or on the overarching query of the best way to change OS drives in a RAID 1 array?

Thanks upfront in your persistence.
