RAID 1 Question - One hard drive fails

[KuJaX]

I understand that if you have a RAID 1 configuration and one hard drive fails, then it will alert you when booting the computer, but you will still be able to boot into your operating system from the healthy drive.

My question to you is that if one drive fails, and you get an exact same model replacement, how do you include that in the same RAID 1 array so that it starts mirroring on that drive again?

Example: Two 250GB in RAID 1. Disk 2 fails but you still have Disk 1 and continue to use and boot into Disk 1 until you receive the RMA back from the hard drive manufacture. You just received the Disk 2 unit back repaired. How would you go about getting the Disk 2 back into the array as if it never failed?

you will need to go into the RAID card's bios and rebuild the array once you've hooked up the new drive.

Enterprise RAID cards can do it in the background while you continue to run the OS. But soho cards I've seen require you to sit there and wait for a few hours while it rebuilds.
