As I know that one of my drives will be totally erase I do not want my C: drive to be mistakenly erased when the raid 1 functions starts. On the a SATA motherboard it does not indicate which, receptacle is for the C: drive. It only indicate 0, 1, 2, 3, 4.

1) The Drive letters are for labeled for Partitions NOT drives!
2) Drives are listed as Drive 0, 1, 2, 3 and so on.
3) If you ONLY have two drives and you are trying to mirror those two then your OS (C Drive) is on one of those and it WILL be erased
4) If you have 3 or more drives what I would do just to be sure is unplug the drive that has the OS on it from the motherboard so that when you go into the Raid Management it will only see the other two drives. Make the raid 1. Once complete turn OFF the PC, Plug back in your OS drive, and turn back on.
If you are trying to make a Raid using a RAID software program within windows it won't even let you touch the drive that has your OS on it because its in use by the OS.

Thanks drt. So you are saying that I should unplug my os drive when I am setting up my raid 1 mirror copy first. I want to create a mirror drive of my os drive so I can remove one of them and leave the mirror copy. Will this work? I am just not clear about unplugging my os drive. I do know that one of the drives will be erased. Let me see if this correct. I am setting raid through bios. So do I disconnect the os drive before or after I go into the bios raid 1 settings?

No when you created ANY KIND OF RAID ALL DRIVES WILL BE ERASED! Not just one! ALL OF THEM.
Are you tying to just make a backup of your OS drive because if you make the raid and then unplug one of them this will defeat the purpose of a RAID 1 and having one of the drives of the raid gone all the time might cause issues. Well not so much with a RAID 1 but your PC will be telling you its degraded all the time.
Are you just trying to make an exact copy of your OS drive?

Are you just trying to make an exact copy of your OS drive?
What I want is to make an exact copy of OS drive(1) so I can remove that drive and use it on another computer and keep the copy in my old computer. The problem that I am having is that my old computer is still operational and both drives do have the same data in them including the os on the drive (2), but when I remove os drive (1) and leave the second drive os (2) it go into repair mode and once it finishes the repair it recycles back into repair mode again at it reboot and it never come on line.
Just do not know how I can make drive (2) the os drive. I have tried the recovery disk on it and it lead to me use an external drive to back up info on the drive which took forever. When it finished and rebooted, well it went right back doing the repair thing. All the data is still in drive (2) and can open it when I put the os drive (1) online. I have tried everything I know, so that why i thought about the raid function. Can you help me please I am exhausted.
