We can rename a drive letter of a disk using PowerShell with the Set-Partition command. An example is shown below.
In the Windows OS, we have E: and we need to rename its partition to the F: You can run the below command.
Set-Partition -DriveLetter 'E' -NewDriveLetter 'F'
You can also run the Get-Partition command and Pipeline the Set-Partition command. For example,
Get-Partition -DriveLetter 'E' | Set-Partition -NewDriveLetter 'F'
If you want to rename the drive on the remote computer, then you need to take the CIMSession of the system and run the command. For example,
$sess = New-CimSession -ComputerName 'Test1-Win2k12' Set-Partition -CimSession $sess -DriveLetter 'E' -NewDriveLetter 'F'
