Hopefully you're still hoping for an answer...

Please excuse my lack of experience in RAID. I did pick up some links for you:

http://www.addonics.com/products/hos.../adsa3gx4r.asp

http://www.digg.com/tech_news/Best_RAID_Tutorial,_Ever_

Try them both. You'll need to read a bit.

Good luck!

raid 0+1 & raid 1+0 is set for miniumum 4 disk, which is probably what the bios recognised when you had the 4 disks in to begin with. raid 3, 4 & 5 are used for 3 disk minimum, check your configuration is setup for either 3 4 or 5. probably what is wrong. (raid 3 & 4 is dedicated parity) (raid 5 is distributed parity). hopefully this should get ya going!
