Q. How can I change the drive letter for a DVD drive using PowerShell?
A. I recently needed to use the E: drive for data in an Azure VM but by default the E: drive is used for the DVD drive. I needed to configure this using an unattended configuration and used the following PowerShell to not only change the drive letter for the DVD drive but then automatically initialize and create data volumes on the two data disks I had added to my VM.
#Change CD drive letter
$drv = Get-WmiObject win32_volume -filter 'DriveLetter = "E:"'
$drv.DriveLetter = "L:"
$drv.Put() | out-null
Get-Disk -Number 2 | New-Partition -UseMaximumSize -DriveLetter E | Format-Volume -FileSystem NTFS -NewFileSystemLabel "Data1" -Confirm:$False
Get-Disk -Number 3 | New-Partition -UseMaximumSize -DriveLetter F | Format-Volume -FileSystem NTFS -NewFileSystemLabel "Data2" -Confirm:$False
