Configuration Manager (SCCM) | OSD | Multiple Hard Drives | Advanced

Ever had multiple disks hardware builds and the Operating System is not getting installed on the expected hard drive…..well here are steps to overcome that.

The script will identify the total number of Physical Disks by ‘BusType’ technology and ‘Size’.

The default configuration sets the ‘latest’ BusType technology and ‘smallest’ sized hard drive as the Primary Disk.   (This can be reconfigured in the script)

The Configuration Manager variable ‘OSDDiskIndex’ will be assigned the disk number of the ‘Primary Disk’ and used in the deployment step ‘Partition Disk 0 – BIOS’ or ‘Partition Disk 0 – UEFI’, ‘Pre-provsion BitLocker’ and Apply Operating System.

Remaining, detected hard drives will be formatted as a simple volume

1. Set Disk and Format – PowerShell Script

Add a ‘Run Powershell Script’ to the task sequence before the step ‘Partition Disk’. 

Type:  Run PowerShell Script

Edit Script: Copy and Paste PowerShell script

PowerShell Execution Policy: Bypass

NOTE : To change the searchable disk BusTypes amend line 62

$diskorder = @(‘NVMe’,’SD’,’SATA’,’SAS’,’RAID’,’ATA’,’ATAPI’,’SCSI’)

Add\remove the BusType you wish to search, with the highest priority first

For more information on BusType read https://docs.microsoft.com/en-us/previous-versions/windows/desktop/stormgmt/msft-physicaldisk

To change the disk drive selection from largest to smallest amend line 68

@{Expression = “Size”; Descending = $True}

2. Configure Partition Disk 0 – BIOS

Partition Disk 0 – BIOS : Select the ‘Windows (Primary)’ volume and Set the ‘Advance options Variable’ to ‘OSDisk’.

The variable ‘OSDisk’ will be used in the ‘Apply Operating System’ to ensure the operating system gets applied to the correct hard drive.

NOTE: There is no need to change the ‘Disk number’, as this was dynamically assigned in the PowerShell script ‘OSDDiskIndex’

3. Configure Partition Disk 0 – UEFI

Partition Disk 0 – UEFI : Select the ‘Windows (Primary)’ volume and Set the ‘Advance options Variable’ to ‘OSDisk’.

The variable ‘OSDisk’ will be used in the ‘Apply Operating System’ to ensure the operating system gets applied to the correct hard drive.

NOTE: There is no need to change the ‘Disk number’, as this was dynamically assigned in the PowerShell script ‘OSDDiskIndex’

4. Pre-provision BitLocker

Pre-Provision Bitlocker :  Under ‘Apply BitLocker to the specified drive’, select the ‘Properties’ tab and change the ‘Destination’ to Logical driver letter stored and ‘Variable name’ to OSDisk 

NOTE: The Pre-Provision is applied to the Operating System as the ‘OSDisk’ variable was assigned in the PowerShell script

4. Apply Operating System

Apply Operating System : Select the ‘Properties’ tab and change the ‘Destination’ to ‘Logical driver letter stored in a variable‘ and ‘Variable name’ to ‘OSDisk‘

NOTE: The Operating System is applied to the correct Drive as the ‘OSDisk’ variable was assigned in the PowerShell script

Log log file of the actions performed can be found at C:\Windows\CCM\Logs\OSD_DiskSearchandClean.log

Downloadable source files can be found at https://github.com/Drakey2000/CommunityHelper/tree/master/OSDDiskFormat

Update : Since writing, Microsoft has enhanced the Task Sequence Step Properties for ‘Format and Partition Disk‘. So check in out

https://docs.microsoft.com/en-us/mem/configmgr/osd/understand/task-sequence-steps#BKMK_FormatandPartitionDisk

This enables you to use scripts to assign variables to all disks, not just ‘OSDDiskIndex‘ and use the ‘Format and Partition Disk‘ in the Task Sequence to dynamically perform actions.
