Newbie problem, basic RAID on Mac question

[lh49]

   

Hi - apologies for the stupidity, but i just cant find the answer to this simple question anywhere. Could someone please explain it to me?

 

I have a 2TB Drivestation Duo on a Mac. I have gone through the "RAID setting" program and have 2xRAID1 discs set up. I restarted my mac and I see 1, 1TB drive which I was able to format in disck utility and its working well.

 

My question is - how do i ever see the other disc? What happens if the primary disc fails? How do i get to the second disc?I understand the rationale of only seing the disk i'm writing to and the drive sorts out the second one, thats fine. But if i needed to, how would i actually get to the backed up data?

 

Thanks hugely.

If a drive fails, then the unit should go into a "degrade mode" running off of one drive.

If you replace the defective drive with another and the unit will automatically restructure it.
