Raid 1 question

[liquidex]

Hey guys my friend needs a bit of help and I know nothing about Raids.

He is using Raid 1 on Windows 7 with the Microsoft driver and one of his hard drives is on the way out.

Is there a specific procedure in swapping out the drive in Windows 7? Also what happens if you want to swap it with a larger drive as well?

Thanks

Think its hardware Raid 1 using the Intel ICH8R chipset but with the default Windows 7 driver if thats any help.
