I have a brand new server with 2 x 80gb hard disks. I want to partition one of the disks so it has a C drive for the OS and a D drive for the data. I then want to mirror it to the other disk. I want both the OS and the data mirrored can this be done? If it can do I mirror the disks first before creating the partitions or do I do all the required work on the first disk and then mirror it? Unfortunately the server has not come with a RAID controller and I am unable to purchase one so I need to do this using the Windows 2000 software. Cheers in advance for your help.
