Last time I showed how to format disks using the Win32_Volume CIM class. If you need to perform this activity on a Windows Server 2012/Windows 8 or later system you can use a couple of cmdlets from the Storage module
Get-Volume | where DriveLetter -ne ‘C’ | Format-Volume -FileSystem NTFS -Confirm:$false –WhatIf
If you’ve not looked at the Storage module before there is a lot of useful cmdlets.
