Re: Script to automate the initialization of disks and creating new volumes inside the windows guest VM ?

The initialisation and the formatting of the new harddisk needs to be done inside the guest OS.

You can use the Invoke-VMScript cmdlet to launch a PowerShell script inside the guest OS.

You can find a good sample script to initialise and format a harddisk in Use PowerShell to Initialize Raw Disks and to Partition and Format Volumes
