    Ownership goes by Sid security identifier so when on seven it's would be owned by the user of that windows with a number which is what your seeing as a missing account the name may be the same in ten but the numbers will be different and if you logged into ten with a ms account it would be different again

    Hi aramil,
    Bad Drive is remote possibility.
    I am always using "Eject Drive" and only remove it says is "Safe to remove it".
    I think, I have no chance to recover Data, CHKDSK already removed all references to Data, all I have is garbage.
    I will erase and Initialize the Drive again, but before I will wait a little until an "Expert" says something about recovering possibilities.

    The problem is recurrent, (see link above) and is known to happen.
    I think the Key problem is changing the Ownership to something else.
    How can it be that suddenly the Drive Ownership is changing and worst to a "Unknown Account". Where from is coming this?
    I think that is a serious Bug, it is a simple way to Lock/Destroy HDD. Scaring is that you never know when it will happen.

    Well, the thing is the HDD Ownership was changed , I was getting the message "Access Denied". I was Logged In System with my only User Account, HDD was working Normally and accessible and suddenly it Changed, who knows why?

    Don't need the references to the data, a good recovery suit will scan the raw disc itself to see if any data can be reconstructed.

    You are confusing two issues, the example you link to is a permissions error with one system OS level event (chkdsk win10) trying to modify another system level's main OS drive (win 7) , the user did not loose the data just access to it, which was restored.

    The Unknown account is your old win8.1 SID as @Samuria posted above, it is machine & user & OS dependent (not just account), if this (user) really was the cause, every time someone used a usb drive to transfer data between computers the second computer would chkdsk and wipe the drives data, which i am sure the internet would of exploded about.

    Yours is a data corruption issue that has nothing to do with SID's. You have access to the drive and data, but it was returning errors.

    The lesson as always stated is have a backup plan for any data you do not want to loose and make sure it is updated on a regular basis.

    Thank you aramil,

    Immediately after, I have seen that in Explorer and I knew at once I had problems, I tried to run "Scan and Fix" the Drive became as if it was unformated with "Access Denied" as with the other user.
    It means the "Onwership" has been changed, why? Why it changed so that it Blocking the access?

    Well, Data Corruption, no HDD Defective, who is the Culprit? And a Repair that was not able to Retrieve Data.
    It might be, that First NTFS table was bad, but the Second NTFS Table was Worst. So far I recall, it was retrieving files that I deleted one Year ago and for sure, the Data has been overwritten several times, so the recovered Files are garbage.
    I think everything is scrambled in HDD, so I have no chance to retrieve Files. I will not spent 100 bucks to get Garbage back.
    This is a Super MCA.

    This HDD was a Backup HDD and I was using it seldom. I have to think well about Security of my Data , if every time I connect a Drive it gets corrupted, I do better buy 1000 HDD, connect them once and never again, just because.

    This happened yesterday, I was so Down and Depressive, I stop working, I had no Head to think not even come here and expose the situation, I am still down, disappointed with all Modern Computing that in Seconds you can lose all data.
    Why did I Upgrade, is the question I am doing now?

    The ownership ussue for external drives is a red herring.
    The owner of root volumes (\) should be TRUSTED INSTALLER or SYSTEM, files and folders under the root can be any authenticated user.

    Ownership of the drive caused UAC to ask for permission or denied access completely.
    Ownership was not the cause of bad sectors.


    To recover your data, you might try
    -- OR --

    Read the instructions carefully.


    I'd like to see your Disk Management

    1. Download dmDskmgr-vg.zip (contains dmDskmgr-vg.mmc)

    2. Open the compressed folder, dmDskmgr-vg.zip
      Double click dmDskmgr-vg.mmc to launch it
      Press the Open button if prompted Do you want to open this file?
      Answer yes to the User Account Control prompt

    3. Press Alt+PrtScn to grab a snapshot of just the Disk Management window
      Open Paint and Ctrl+V to paste it, then save the image

    4. Attach the image to a new post
    Tip: you can drag the middle bar up
    to show more of the bottom pane



    (just don't drag it too far up
    - I also need the information in the top pane)

    Thanks

    Hi Slatybart,
    Thank you for the Links, I will try them.
    I can not imagine that there is something wrong with HDD, so I am tending something went wrong with Security/Ownership.
    Anyway I am not expertise on new Windows Features, but I have long experience with PC.

    About Disk Management, I just formatted the Partition where Upgrade Win 10 was, now I am restoring Win 8.1 from an older System Image.
    Is it enough to open native Windows Disk Management? Or do I need to use the one you said?
    I have 2 PC, you mainly want to see the "bad" HDD or the Whole system of the PC where Win 10 was installed?
    Thank you.

    The disk management in the zip file is just a modified console - it formats the columns and provides an average split

    If you make certain that the columns and panes show the most information - sure, disk management on your machine can be used.

    If the screen shot you post does not show the information needed, I will not ask for another screen shot.

    Show me all drives that concern you (I'm more interested in the bad HDD) but it is useful to see a machine as a whole when issues arise.

    With a Google search on "ownership hdd" I came to the ref:
    Owner of Files and Folders - Change in Windows 10
    See also the comments.
    The idea is to startup the PC with a Linux (Ubuntu) CD and see whether you have access to the HDD. Linux ignores ownership and security settings; for further details see the link. As a last resort, you may give it a try.
