I have 2 SATA HD of 1TB each. My motherboard has a controller which supports RAID. I would like to configure RAID-1 in order to avoid lose of information if one HD fails, however I have some questions:
1. I'm not sure if my HD are equivalent. Both have the same number of sectors, but one of them has a partition of 8MB created (and I don't know why).
2. I know how can I configure RAID from my BIOS, however, I'm worried about data: one of my HD has valued data and the other could be formatted. What will the controller do when discs has different content ? Will the RAID controller replicate one of my disks to the other at starting ?
3. My goal of configuring RAID is to avoid lose of data, however, how will I know when a HD fails, as I understand when one disk fails in RAID mode, system can continue working by just using the other.
Thank you. My motherboard is a GigaByte S-series GA-E7AUM-DS2H.
