You need to initialize the drives to let them run in normal operation, just as you would when you buy a brand new drive and chuck it in your computer. Initialize and do a quick format and you'll be laughing.
If setting the controller to "normal" mode doesn't allow windows to see the data then your only choice is to put it back in RAID mode, backup all the data, put the controller to "normal" mode, initialize & format the drives, then restore the data to them.
Doing so will overwrite/format/kill the data on the disks, which IS NOT WHAT YOU WANT.
Instead, burn an Ubuntu Linux livecd, boot from it and try to access your RAID contents using software RAID available in Ubuntu Linux. It should be ready immediately:
- click 'try ubuntu' so it won't install anything
- click the Places menu, click Home
- in the new window that opens, there is a left panel that may contain "... GB Filesystem" link you can click on. When doing so you should see your data appear on the right side of that window.
- if it works you can use the network to copy off data
This procedure won't work anymore if you click OK in the screenshot you posted. So think twice!
I am sorry.. I didn't read that you wanted the data. I thought you just wanted the drives ready for use lol. I was VERY tired when posting my last reply. Anyway sub mesa is spot on, follow his instruction.
