Restore - Problem that Diskcopy image is 'write protected'.

Hi there - I wonder if I might request your advice.

I have Aomei Backupper Professional installed and over time wrote several "disk backup" to an external diskdrive. 

Recently, I discovered a corruption problem with the master boot record in Windows 10 and couldn't restart the computer as it was in a continual automatic repair loop. I determined it was advisable not to do a full restore from a disk backup as I would risk repeating the start up problem. I reinstalled windows 10 and now have a functioning computer. 

I would now like to access my files and programs from a disk backup so I can copy them to the main drives. To do this, I had followed the instructions for the Aomei Backupper "Explore Image" function and can see a list of folders under new drive headings.

Unfortunately, when I try to access the user folders I am denied permission and then when I attempt to change the permissions to allow access, a dialogue box appears which states that "an error has occurred in applying security information". It also states that "The media is write protected."  This means that I am unable to open the relevant folders or access files.  

I would appreciate any advice to overcome this problem - especially the write protection. 

Keep well

    Please try another File Explorer than Windows Explorer. This is a known issue.

    Google on Q-dir.exe for an alternative explorer.  You can also use CMD.exe, the Windows Command prompt. You may need to run these as administator in the latest versions of Win10.

  • Thank you for your suggestion.  I'll seek a copy of Q-dir soon.  You also refer to the Windows prompt - is there an instruction that can be used with the prompt to address the problem?  Thansk again.  Keep well Paul

    DOS commands are the first PC commands ever. Bill Gates was at the beginning of this in the 80's. So there a tons of books and internet help pages about DOS.

    DIR, CD, COPY or XCOPY are the commands you might need.

  • Thank you for your advice.  I successfully managed to use Q-dir to copy files from the disk backup image to an external drive so I could reconstruct my documents folder. This fixed the problem and I now have a functioning computer with my files intact.   

    Later in order to learn something about the commands you mentioned I mounted a disk copy image and then used the Command Prompt (Administer) to copy files to an external drive using the xcopy command. This took longer - but I think it is very useful as an alternative approach should the Q-Dir approach fail.

    I'm wondering whether the "write protection" issue I mention in my original post is normal for using Aomei disk backup - given that I'm only using standard Windows 10?

    Keep well
