The RAID controller (onboard software or hardware) will tell upon boot which drive is dead, usually by the drive's ID (that the manufacturer gave it, not what you put in windows).

If a HDD does die, you replace it, and the raid controller will use parity data on the remaining drives to build the new drive. The quality and speed of the rebuilding process is Dependant on your controller.

In raid 5, whatever number of drives you have, you lose 1 drive, so n-1. In raid-6, you lose 2 drives.
