i am thinking of setting up a raid array 1, and is i understand it i will use 2 drives exactly the same and this will run by making a mirror image on both drives so if one drive fails i will still have a o/s to work on.but if a drive fails i have to reinstall a clean windows o/s to setup raid again when i install a new drive.i cant quite see the point of this as if you backup everything as i do to a small file server i have built for backups or if you backup with dvd disc just the same.if my single drive fails i still have to install windows as this would take just as long, so what is the point of raid.i could understand it if you could recover raid without having to reinstall windows.is there a way of recovering raid without having to do this.
