Breaks the mirrored volume with focus into two simple volumes.  Syntax:  BREAK DISK= [NOKEEP] [NOERR]      DISK=    Specifies the disk that contains the mirrored volume. This disk                 is given focus and does not retain the drive letter or any                 mount points. If the mirror on the specified disk is used as a                 system or boot partition, the command fails.      NOKEEP      Specifies that only one of the mirrored volumes is retained;                 the simple volume on disk N is deleted and converted to free                 space. Neither the volume nor the free space receives the                 focus.      NOERR       For scripting only. When an error is encountered, DiskPart                 continues to process commands as if the error did not occur.                 Without the NOERR parameter, an error causes DiskPart to exit                 with an error code.      Applies to dynamic disks only. Breaks the mirrored volume with focus into     two simple volumes. One simple volume retains the drive letter and any     mount points of the mirrored volume. The other simple volume receives the     focus so you can assign it a drive letter.      By default, the contents of both halves of the mirror are retained. Each     half becomes a simple volume. By using the NOKEEP parameter, you retain     only one half of the mirror as a simple volume, and the other half is     deleted and converted to free space. Neither volume receives the focus.      A mirrored volume must be selected for this operation to succeed.  Example:      BREAK DISK=2
