I'm in the ACU/adaptec bios utility. All four drives are initialized.

I go to Create an Array, select all four drives. It only gives me Raid 1/10/1EE options - but no RAID 5.

What am I doing wrong?

That card doesn't support RAID 5.

From Adaptec's page for the 6e-series adapters:

  • RAID levels 0, 1, 10, 1E, and JBOD

You know..That makes an amazing amount of sense. I just realized that myself. I could have sworn it said Raid 5 on the product page when I bought it. DOH! – NoCarrier Jun 15 '13 at 2:28
