RE: New HDD not being recognized by SAS controller on PowerEdge T410

Hi Daniel,

I've heard that hot spare is not a good backup system and using RAID system is more efficient since complete data is preserved. Not sure though.

On another note, I have a windows 2008 R2 server with two 500GB. Since it's getting full, I would like to upgrade and use 2x 2TB instead. At the moment when I reboot, it says both drives are degraded and get 78 and 79 error, but it boots to Disk 0 fortunately. So I am kind of worry that the other one goes down..can't effort..

How should I go about this? take Disk 1 and put new 1TB and then SAS Controller to tell it's part of RAID 1?
