Windows 10: What is local disk Z? Solved

    What is local disk Z?


    I see drive C and drive D, but don't know what local disk Z is . It's 256 mb in size, and about half full. I can't open it to see what's on there since I get a message, "permission denied." It's been there for a long time, but I'm just now getting curious.

    I've seen this also, I think you'll find it's a partition of the main "C drive" that shouldn't show. A restart usually gets rid of it for me.
    Hope this helps.

    I believe you're right, except in my case restarting doesn't change anything. A little more investigating seems to confirm it what you said. Thanks.

    {by me, from a related thread} Do not delete it, it's necessary for the computer to start. I have hidden system partitions appear as a Z drive too, usually after doing a virtual drive mount. Here's how to remove the letter from the drive to keep it from appearing under This PC (see screenshot of command prompts) window) -

    Win+X/Command Prompt (Admin) {hit enter after each following command, observing spaces and letting each command finish}
    diskpart
    list volume
    select volume #
    {whichever # is assigned to Z, example is 4, as if that appeared next to Z; eg- 0 to remove E)
    remove letter=Z
    list volume
    {not shown, but run to verify letter was removed}
