Two HDDs: one SATA, one IDE. Spares, not bootable OS partitions. Can make RAID1?

[skyshock21]

I have a ~250GB SATA drive that I like to use as a spare media/storage drive. I came upon another drive about the same size but it's IDE. I figured I'd make them one logical volume using JBOD RAID, but then figured I'd be better off mirroring them in case one dies. How do I create a RAID1 array using the existing disk w/ data (/dev/sdc1) and mirror it to the newly added disk w/ no data (/dev/sdb1)?

I'm using Ubuntu Intrepid Ibex as my OS.

Yes, you can. Take a look at Falko's guide in http://www.howtoforge.net/how-to-install-ubuntu8.04-with-software-raid1 for the basic commands for creating RAID devices

To set up RAID1 on an existing system, take a look here:
