I use Windows Vista Ultimate, and have four disks of 500GB. Windows is already installed on one disk, the systemdisk.

Now I would like to mirror the system disk using Windows built-in software raid. How do I activate it?

What do I have to do in the systemdisk? do I have to transform it to a dynamic disk first? How about the other disk, should I format it first and then transform it to dynamic, anything more I have to do?

All you need to do is:

  1. Go to Computer Management > Disk Management

  2. Right click on your main disk (not partition) and choose Convert to dynamic disk...

  3. Right click on your main system partition and choose Add Mirror

    alt text

  4. Select the disk you want to mirror to.

All done!

I don't have an "Add Mirror..." option in that menu. I have made the disk "dynamic". Any suggestions? –  Jonas Sep 10 '10 at 14:42
    
Windows Vista dosn't seem to have this feature: superuser.com/questions/187671/… –  Jonas Sep 12 '10 at 11:50
