Hiya,
Unfortunately Superboss is right. The cards you have are fakeRAID (software based RAID).
This will explain for you.

The only thing I can reccomend is trying to sell the cards on eBay and try to get some money back for them to buy other cards with the functionality you require. Me personally would recommend the 3ware and adaptec cards, but again some of the adaptec cards are software RAID (1420sa for example).
If you are looking for a card and want to know which are hardware / software based cards, then look at this website.
