I have a system running windows 7. The main root drive has 2 partitions on it which were automatically created by the installer. I have another duplicate hard drive that has been installed, formatted and both drives are now dynamic. Can't do the right click and mirror drive????

Is there something I need to do?

Any help would be much appreciated....

    Delete the partition on the second hard disk. Then when you right click the original partition, you should see the mirror option.

    Refer to this KB Article: (It's for Windows 2003, but should be similar to Windows 7)

    Thank you for the info. I did try that but it will only mirror part of the drive (single partition) and not the whole drive. For whatever reason, when Win 7 installed it created 2 partitions. partition one was "system reserved" and the other was a normal partition.

    So I can mirror part of it but not the whole drive. Tried right clicking on the left where the whole of drive "1" is located but it does not offer an option to mirror the whole drive?

    Any thoughts?

    It did work. Just had to do each partition separately. So did the mirror twice.

    Thank you for your help.

    If you want to mirror the whole disk, go for a hardware solution and buy a cheap SATA-Raid-Controller eg Adaptec 1220SA or similar.

    Using Windows Software Mirroring is a pain anyway, because if one of the drives fail, you have to manually edit boot.ini in order to boot.
