  1. Mystery drive


    Available drives \\?\Volumes(22100F1af1f9-4a2d92. That is an extra drive that is showing. It shows protection settings off for also. And I noticed the shared PC account manager shows catastrophic failure. Can anyone help me out with this.

    :)

  3. mysterious local drive z:

    Yes, I would say it most likely is Win10 doing this, as has been experienced by
    many other people who've created numerous threads about this same issue of a mysterious Z: drive that appears and disappears seemingly at random. (According to one theory Z: is the ESP or recovery partition mistakenly being assigned a drive letter,
    and the issue is possibly related to Windows updates.)

    As such, my suggestion would be to map to a different drive letter, and ignore the other ridiculous suggestion made above. Most definitely everyone who's seen Z: come and go doesn't have a broken Win10 copy necessitating a reinstall. This is just another
    Windows bug.

    Recovery Drive Mystery


    Thank you Bree, the details you provided largely clears up the 'mystery' except that I am not aware that I opted not to backup system files (the default). The list of files amounting to around 4 GB is the sort of thing I was expecting. Plus, when you refer to the Boot etc. files taking only a few minutes to create, the time taken in my attempt to create the Recovery Drive was over an hour! (despite it being a clean, formatted drive). So it seems to me that some mysteries remain.

    Anyway, I will now try again, and look out for the backup system files option to make sure it is on..
