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

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:
- From the Start menu, select Programs, Administrative
Tools, then the Computer Management Microsoft
Management Console (MMC) snap-in.
- Expand the Storage branch, and select Disk
Management.
- 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.)
- To confirm your selection, click Yes.
- 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.

If you lose part of a fault-tolerant volume (e.g.,
by hardware failure), the OS will display the
message A disk that is part of a fault-tolerant
volume can no longer be accessed. The drive
will still be usable, but you won’t have the mirroring
capability. To break the mirror set, complete
the following steps:
- From the Start menu, select Programs, Administrative
Tools, then Disk Administrator.
- The OS will display a message that a disk
is missing.
- Click on the mirror, and select Break Mirror
from the Fault Tolerance menu.
- Confirm the action.
