NVIDIA RAID 1 replacement HDD query.
 

I had a DISK BOOT FAILURE message on my PC the other day. I was using RAID1 with the Sil3114 controller. I tried one of the 2 drives into the other SATA sockets and it fired up fine, the other drive gives error beeps and won't boot. I'm assuming it has failed. On the motherboard sockets 1-4 are for NVIDIA controller SATA-II and 5-8 are for the Sil3114 SATA-I
I don't think I have the NVIDIA controller software installed so its using the one built into XP?
If I was install the NVIDIA software for RAID1 and added a new SATA-II HDD would it allow me to mirror the data from my working drive on to the new one?
I was looking at one of the WD RE3 320Gb drives.
Then if I removed the 160Gb drive and added another WD RE3 drive would it allow me to mirror that one so I'd have 2 x 320Gb drives and could put the 160Gb into a caddy for external use.

Might be silly impossible questions but I can't find any info to say it will or won't work.
