I want to retrieve information about the OS images that are contained in a wim file.

"dism /Get-WimInfo /WimFile:d:\sources\install.wim "was typed in the command line (system manager)

but error 21 happened "the device is not ready". Actually I know little about computer and don't know how to fix it.

the log file says as follows,

Is your wim file located on a read-only device? Try to copy the wim to an HDD and then run the command again.

Hi,

According to the DISMI log, it seems like there is a problem with the WIM file. However, you can try to change a location for test to check its information.
