Intel Matrix Storage Console Raid 0

[wfarid]

I have a gigabyte EP45-UD3P board and I recently put in 1.5 seagate terabyte drives. I previously had a raid 0 on the gigabyte raid with seagate 1tb drives but when I tried to do it on them with the 1.5 drives, I couldnt install vista. So I switched to the intel ICH10R and every day or two days it keeps saying that one of my drives (same drive/port) fails. I've rebuilt the raid 3 times so far. Is the drive itself corrupted or is it just the intel raid?

Using Vista X64 ultimate. And intel matrix storage console 8.6
