For the last 18 months I've been running two Seagate Barricuda LP (2TB) in a RAID 1 configuration on an external MediaSonic (HUR1-SU3S2) box as a "data" drive e:\. A week or so back the power went out and the box never came back up. Dead.
The good news is the drives are fine. I've checked them both by plugging them directly into the SATA ports and everything is there. I've been dutifully copying the data to another RAID box. Now, rather than buying a new RAID box or waiting weeks for an RMA I would like to plug the drives into my ASUS M5A88-V EVO motherboard which also supports RAID (SB850 chip).
Question: do I have to wipe the drives and start from scratch and restore, or, can I use one drive with complete data, format the other drive and have the motherboard controller rebuild from one of the drives? It would save me a lot of time if I didn't have to restore all the data to the new array. Thx.
Well first I would would backup the data anyways. Better safe than sorry!
Then proceed with your plan as it should work exactly the way you describe but if it doesn't and something goes horribly wrong (like the source drive dying during the rebuild completes) then you have the backups you made before starting to fall back on.
