  • ‘Add Mirror…’ option is grayed out in Windows’ Disk Management

    How to ‘Add Mirror’ on a disk containing data when the option is grayed-out although you have another very similar disk available and empty? Check that your two disks are “Dynamic” and shrink the volume on the disk with data!

    I had a 2 TB disk with a unique volume (on one single partition), containing data.

    I did add a new 2 TB disk to be used as a mirror of the existing one. I went into the Disk Management tool to “add Mirror” but found that this option was not available. The menu was disabled:

    Add Mirror Grayed Out
    Add Mirror Grayed Out

    First thing to check: the two disks to be used must be “Dynamic”. Right-click on “Disk x” to “Convert to Dynamic Disk …”.

    Next, to be able to create a mirror, the system needs some free space to create its own reserved partition on the disk. So, right-click on the Volume of the disk with data to “Shrink Volume…” (Try first with 1 Mb). Once the disk has been shrunk, the menu “Add Mirror…” becomes accessible.

    Add Mirror Enabled
    Add Mirror Enabled

    Et voilà.


    • It does not matter if the disks are MBR or GPT.
    • Once the volume shrunk, you will possibly have to reboot.
    • If you encounter an issue while adding a mirror, do a “Check Disk” (Properties > Tools > Check).
    • If you can really not get rid of the error “DiskPart has referenced an object which is not up-to-date.” although rebooting, do an “Extend Volume” of 1 MB! (Sound silly, I know…) and then “Add Mirror”.
    • In my case, while the disks were re-syncing, I did remove the mirror, did an “Extend Volume” to reuse the whole free space, and was still able to do an “Add Mirror”.

    Mirror using DiskPart

    • Run DiskPart in a cmd prompt started as Administrator
    • list disk
    • select disk x [x=disk containing the volume to be mirrored]
    • list volume
    • select volume x [x=volume to be mirrored]
    • add disk x [x=disk to be used for mirroring]


  • Check if Samsung Smart TV is alive with Php Server Monitor

    If the TV is on, querying on http://IP:8000, you get the response:

    Server is running...

    If the TV is on, querying on http://IP:8001/ms/1.0/, you get a response like:

    When the TV is Off (powered off or in standby mode), you won’t get any response from those ports but:
