Default Raid 5

I have 3 x 1 Terabytes disk running on Raid 5 and 2 x 500GB disks on Raid 0 so that they all combine and make up 4 Terabyte on Raid 5, the problem is upon boot up raid 5 only sees the 3 x 1 Terabyte disk and does not see the 2 x 500GB disks. Any ideas on how ro resolve this?

Your RAID is showing correct values. You are setting RAID 50, right? Here is simple math:
Code:
3 x 1 Terabytes disk running on Raid 5 = 2 TB
 2 x 500GB disks on Raid 0 = 1 TB
----------------------------------------
Total 3 TB
-------------------------------------------
Am I missing something? Here is a quick link to RAID calc:
