Configuring Mirrored sets

I have a 2 HD unit, the primary C:\ drive  (OS) drive is 18G, and the d:\ is 9G.
This is what I did with the 9G drive:  In Disk Management, right-clicked in area marked unallocataed then choose New Volume, and then clicked next.

When I got to select the Volume type ALL is grayed out but simple.
Now it is SCSI and I'm assuming one controller card.  But shouldn't I still be able to do a mirrored with one drive controller.
Now the other issue maybe if I'm correct the C:\ drive is 18G, and the unallocated is 9G.
Do I need to make the unallocated drive 18G?

There is no option in the BIOS to do a RAID configuration.  So that is out.

Thanks again for all your help.

How do you expect to make an EXACT copy of the 18GB drive onto a 9GB drive?  
To put it another way, if you have an 18" Pizza pie, how do you make it fit onto a 9" pan?

If you want to mirror the C drive, you need to replace the 9GB drive with another drive AT LEAST as big as the C: drive.

As lee says you will need to have the second HDD to be as big or bigger than the C: drive You will also have to convert the system and the destination disks to dynamic disks before you can mirror (If you have not already done so)

ECHO both answers

you don't have to set the drives to dynamic if you have a raid controller card. they only have to be dynamic if you are doing a "software raid". but yes, as leew and terrygreensill said you can't mirror an 18 gb to a 9 gb. you can do it the other way around but will be waisting half of your drive space on the 18

if you have a raid controller card you will install 3rd party software that you can manager your raid array either through a windows application or through an extra bios. i know with adaptec they have the adaptec storage mangager for windows and you can do a ctrl-a in post for access to the bios contoller configuration.
