A mirrored volume, also called a RAID-1 records the same information on two hard drives making them redundant drives. If you write data to a drive, you will be actually writing it on 2 drives. In order for this to work, you should have 2 identical hard drives. They could be different sizes BUT, the smallest one will be the actual “mirrored drive. An example is, if you have a 1 TB drive and a 1.5 TB drive and you mirror them both, the 1 TB will be your combined (mirrored) drive. Continuity in any business is always crucial which is why its a great idea to mirror your server drive and also the workstations.

Our server installations consist of mirroring the 2nd hard drive. We isolate this as the data drives. At the end of the day, this is what we care about, the data.

Here are the steps in creating your mirrored drives;

  1. Do a right click on your “My Computer” icon and click on manage. Click on Storage, Disk Management.
  2. Right click on a disk or unallocated space of a used disk and select New Mirrored Volume.
  3. Select the second disk – the size should be as large as the disk or partition you want to mirror.
  4. The next screen shows the default assigned drive letter, you can set any available letter from the drop-down list, while, you can also create a volume without a drive letter or mount it in an empty folder.
  5. In the next format partition screen, it is recommended to leave the default file system and allocation unit size settings while type in a meaningful name in the volume label text field.
  6. You are basically done.  Click Finish.
