A. You can use the DiskPart utility from the Windows 2000 Server Resource Kit or the Win2K Professional Resource kit to either create a new mirrored disk or mirror an existing disk. (Be aware that Windows XP doesn't support mirrored disks.) To create a new mirrored disk, perform the following steps:

  1. Download and install the DiskPart utility from the Microsoft Web site.
  2. Go to Start, Run, then type cmd to start a command-line session.
  3. Type diskpart to start a DiskPart session.
  4. Type list disk to list the current disks. The list will look like
       Disk ### Status Size  Free    Dyn  Gpt
       -------- ------ ----  ------- ---- ---
       Disk 1   Online 28 GB 6621 MB *
       Disk 2   Online 12 GB 12 GB   *
       Disk 3   Online 29 GB 29 GB   *
  5. Type select disk 2 to select disk 2 as the disk on which you want to create the mirror.
  6. Type create volume simple size=100 to create a new volume.
  7. Type add disk 3 to add disk 3 as the new disk that will become the mirror.

To add a mirrored disk to an existing disk, perform the following steps:

  1. Download and install the DiskPart utility from the Microsoft Web site.
  2. Go to Start, Run, then type cmd to start a command-line session.
  3. Type diskpart to start a DiskPart session.
  4. Type list disk to list the current disks. The list will look like
       Disk ### Status Size  Free    Dyn  Gpt
       -------- ------ ----  ------- ---- ---
       Disk 1   Online 28 GB 6621 MB *
       Disk 2   Online 12 GB 12 GB   *
       Disk 3   Online 29 GB 29 GB   *
  5. Type select disk 1 to select disk 1 as the existing disk that you want to mirror.
  6. Type list partition to list the current partitions. The list will look like
       Partition ### Type         Size    Offset
       ------------- ------------ ------- ------
       Partition 1   Dynamic Data 10 GB   32 KB
       Partition 2   Dynamic Data 6001 MB 10 GB
       Partition 3   Dynamic Data 6001 MB 16 GB
       Partition 4   Dynamic Data 6621 MB 21 GB
  7. Type select partition <partition number> to select the partition for which you want to add a mirrored disk.
  8. Type add disk <disk number> to add a new disk, which will mirror the disk you selected in Step 5.
