Unable to restore large .vhd due to automount

[inator1192]

I hope this helps others with the same issue...

Hi, I ran into this error a couple of times and was unable to restore a .vhd to a new drive.

Can't write on physical drive. It's probably mounted.
You need to put it off line before to be able to write on it.
Microsoft choose this way for security reason...
It's nice for us and avoid to overwrite a non wanted drive.

The .vhd was about 220GB, so it took quite a while and I never made it to the end.
It appears like Windows was automatically rescanning the disks and mounted the the drive I was currently restoring.

I reproduced this behaviour by manually rescanning the disks while restoring, which produces the same error.

I then disabled automount in diskpart, ("automount" to check current setting; "automount disable/enable" to change the setting) started a new restore attempt and it worked.

Could this command be integrated into the program?

On start of a restore session -> "automount disable"
End or Cancel of restore session -> "automount enable"

(don't forget to re-enable automout if you had the same issue and found this)

А можно просто форматировать физический диск и всё пойдёт как по маслу
