Question about linux and AMD based chipsets/onboard raid

[Brian Cluff]

Did you zero the drive all the way to the end, or just the first part. 
Also maybe you zeroed the partition and not the drive? Many of the raid 
superblocks are at the very end of the drive, and it would still be 
catching them if you haven't done the whole thing.

I really think this is whats happening since the Device Mapper is trying 
to grab hold of it.
