I have a text file which has contents listed due to commands

Is there a way I can script using PowerShell/Batch that can tell me there is no Letter (Ltr) assigned to volume 4. It should say that "no letter is assigned for this Volume 4".

Note: I have tried already the below way, but I think it's not good way of getting the result.

Don't mess around with a text file - just query the partitions directly in PowerShell.

$nodriveletter = Get-partition | where (-not $_.driveletter) -and $_.type -ne "Reserved" |select disknumber,partitionnumber

$nodriveletter

disknumber partitionnumber
---------- ---------------
 3 2

You can then do a Foreach on the results to process any unconfigured partition.

If you want to know what letters are already in use, get all the partition information and extract the results you want after.

$Partitions = Get-partition | where $_.type -ne "Reserved" 
$noDriveLetter = $partitions | where -not $_.driveletter | select disknumber,partitionnumber
$driveletters = $partitions.driveletter #grabs all driveletters in use

  I suggest you do Get-Partition | fl to look at the properties you can inspect in this cmdlet (it's really getting the data out of WMI). In this instance, you could make the Where clause $_.type -ne "Reserved" -and $_.disknumber -eq 0. Since I don't know your hardware, you will have to experiment.
