Thanks for your quick reply. I'm using X-RAID. As I said i'm new to all this. When I put the new second disk in it to hours and hours to be ready. does that mean that if the first disk went down I could just put the second disk in the first bay and still be able to access my data from it if its showowed already?

When you add a disk it has to be synced into the array. The drives have to be synced sector by sector. If a disk (e.g. disk one) fails you should not reorder the disks. If disk one fails, disk 2 would remain working fine in bay 2 and you could replace the dead disk with a new disk in the first slot, there would be a resync and redundancy would be restored.

If both disks failed or some other mishap (such as those mentioned in the article I linked earlier) if you have a backup (e.g. on a USB disk) you could put two new disks in the ReadyNAS and then restore the data from your backup (e.g. USB disk).
