Windows 10: mount-diskimage command says file is corrupted yet file is fine with third-party mounting...

title says it all tried mounting a 100% verified non-corrupted 1440k image file I don't care what you think I love retro tech and VM's yet mount-diskimage returned the "file or directory is corrupt"is there an undocumented limit of minimum size or file system? if so why is it still unlisted?the file has been verified after each failed attempt to still contain the fat file system and files it had for testing purposes using IMdisk as it is the nicest third-party utility that is not expensive to useam I crazy? is sfc broken? is the powershell command broken? is it just a limit nobody bothered

Error when mounting ISO files

Hi,



Thank you for writing to Microsoft Community Forums.



I understand when you are trying to delete/rename/move the ISO files after mounting it you get an error message. It could be possible that the ISO file is mounted and that is the reason you are unable to modify it.



I suggest you to eject the ISO file and then try to modify it. Please follow the steps mentioned below:

1. Press Windows key + E, to open
   File Explorer.
   
2. Click on This PC on the left pane, you will find the mounted ISO file.
   
3. Right click on the ISO file and click on Eject. Try modifying the ISO file now.
   

Please reply with the status of the issue, we will be glad to help you further.



Regards,

Cannot mount ISO files (neither via PowerShell nor via Explorer), Win10 pro 1909, error 0x80070079

Hi all,

I recently found out that my fairly fresh Win10 installation cannot mount any ISO files (which are totally fine because other tools can open and extract them) whatsoever. When I try to do this in Windows Explorer
or in the PowerShell, for several minutes, nothing at all seems to happen before I get an error message. The explorer just says there was a problem mounting the file; PowerShell writes the following:

Mount-DiskImage D:\tmp\90f226a1-3cad-4bd7-a047-fc0609afcbab.iso

Mount-DiskImage : The semaphore timeout period has expired.

At line:1 char:1

+ Mount-DiskImage D:\tmp\90f226a1-3cad-4bd7-a047-fc0609afcbab.iso

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : NotSpecified: (MSFT_DiskImage ...torageType = 1):ROOT/Microsoft/.../MSFT_DiskImage) [Mou

nt-DiskImage], CimException

+ FullyQualifiedErrorId : HRESULT 0x80070079,Mount-DiskImage

The OS in question is a Win10 pro (1909, build 18363.900, latest patches, 2004 is not available for my machine yet); as far as I know, this hasn't worked since I freshly installed the PC back in April.

What I've done so far:

• I disabled the anti-virus,
• have checked that ISO files are still associated with windows and not some third-party tool,
• checked that the 2TB NTFS SSD is okay,
• copied the ISO files to different locations,

but nothing seems to work. How can I get my Win10 installation to open ISO files?

Any new/further ideas are appreciated. I've seen posts claiming to solve this error for older Win10 versions, but not for 1909, and none of the "solutions" I've found so far work for me.

 

Error while mounting ISO

I've tried a variety of methods to mount various ISO's (which are fine, I can open them in 7ZIP) and no dice.

The powershell method gives me an error message...

mount-diskimage -imagepath "X:\new build\DAW\NI Installers\cuba.iso"

mount-diskimage : The semaphore timeout period has expired.

At line:1 char:1

+ mount-diskimage -imagepath "X:\new build\DAW\NI Installers\cuba.iso"

nt-DiskImage], CimException

+ FullyQualifiedErrorId : HRESULT 0x80070079,Mount-DiskImage

This is a brand new Windows 10 install (1909 build 18363.535), everything is up to date. Antivirus is disabled.

The only thing unusual here is that it is dual boot.

Can anybody help please.
