Can I create a RAID 1array with drive that already has data?

I am moving an IDE drive from a customer’s old desktop into his new one. I want backup the old drive (drive 1) to a new drive (drive 2) before moving it to the new computer. Afterwards, I want to setup a RAID 1 array using both drives 1 and 2 so that there will be a backup when drive 1 eventually fails. I plan do use the Windows disk management utility rather than a physical array.

Is there a way to setup mirroring with a drive that already has data on it?
