Iv got two hard drives each 200GB and i want to get them configured into RAID 1- which is mirrored. the first HD is the one im running my entire computer off the second is just basicly sitting there. i went onto Disk Management and i saw the first operating HD named Disk 0 and it said "healthy (system)" and the second HD named Disk 1 said "unallocated". so the computer knows its there and i am just wondering if there is anyway to make it into a RAID 1 with out formatting my working HD or loosing any data. Thanks
