Alexander,

All I can say is THANK YOU! Seriously solved one of the most
frustrating things for me. Not to neglect everyone else you offered
their working methods but the suggested steps above were perfect and
worked spot on! I can't believe how easy that was! I now have exactly
what I wanted...a working Arch Linux server running Software RAID1 on
both drives. I will create my own Wiki even though I now now I was
just doing the right step at the wrong time...

Thank you all for an awesome community of assistance and getting me
right where I want to be!
