If a mirrored SATA drive fails, how does it notify the user of the failure?

I am in the process of building a PC with mirrored SATA drives. It’s a Dell Inpiron 520 which has a nVidia RAID controller.

While there are many things I can test, obviously creating an intentional drive failure to see how the RAID recovery works would be a costly test.

If/when the mirrored drive fails, does it give a Windows system event message? Does it shutdown Windows, go blue-screen, or do something else nasty? I’ve got several PCs which are CCTV DVRs running mirrored drives and I have yet to see a mirror fail….
