How do I break a mirror set (RAID 1) in Windows 2000?

A. Breaking a mirror set won’t result in data loss but will give you two volumes with duplicate data.

To break a RAID 1 set in Windows 2000, perform the following steps:

  1. From the Start menu, select Programs, Administrative Tools, then the Computer Management Microsoft Management Console (MMC) snap-in.
  2. Expand the Storage branch, and select Disk Management.
  3. Right click the mirror volume you want to remove, and select Break Mirror from the context menu. (In this step, you can also select Delete Mirror to remove both volumes that make up the mirror, but you lose the data on it.)
  4. To confirm your selection, click Yes.
  5. Another dialog might warn you about possible data loss on the broken mirror. Click Yes to continue.

You will now have two volumes, so you might want to delete the unwanted mirror to avoid confusion.
