    The Get-Partition cmdlet will get that information for you.

    Get the list of server names into an array and then use the array as the argument to the ComputerName parameter of Invoke-Command. The script block used on the Invoke-Command will contain the Get-Partition cmdlet and any other code you need to extract the information you need in the format you want. The result will be an array of the results from each server.

    The challenge is the number of servers.

    Third party software can be used to convert MBR to GPT without data loss.

    These are commands that could be added to scripts:

    Viewing diskpart > list disk results for each server indicates whether the drive is MBR or GPT.
    Alternatively powershell > get-disk

    Try this: 

    Invoke-Command -ComputerName (Get-Content D:\disk\servers.txt) -ScriptBlock {Get-Disk} |
    Select-Object PSComputerName, Number, PartitionStyle |
        Export-Csv c:\junk\disks.csv -NoTypeInformation

    I'm not sure where the $LogDate is used so I just omitted it from the example.

    You can import the CSV file into Excel.

    Hello Anil,

    If you add a brand new disk to your PC and it doesn't show up in File Explorer, you might need to add a drive letter, or initialize it before using it.

    You can only initialize a drive that's not yet formatted. Initializing a disk erases everything on it and prepares it for use by Windows, after which you can format it and then store files on it.

    Disks can be divided up into multiple chunks called partitions. Each partition - even if you have only one - has to have a partition style - GPT or MBR. Windows uses the partition style to understand how to access the data on the disk.

    Do Check the link below, to get to know About partition styles - GPT and MBR
