Ok so I think I have found the issue. It appears that the device must be rebooted after running the diskpart command, since it appears that there are some temp files that are created by MDT when the boot image is loaded on the disk. I have found the below GitHub page which looks quite good, I will need to do some more testing. GitHub - cregx/mdt-cleanup-harddrive-winpe: Win32-based UI application to erase the primary hard disk as part of a Lite Touch installation (WinPE / Microsoft Deployment Toolkit (MDT)). Regarding the disk setup in the BIOS, we set all laptops to AHCI as standard anyway, thanks for the suggestion though. I also found the below which looks very nice indeed, which might work better as a long term solution for all MDT related tasks anyway, but again this will obviously need to be tested.

Thanks for responding anyway.

Hello, I am also have the same issue, but I can't even get the command to run I just get a task sequence error. Did you ever manage to get this sorted? If so would you be able to tell me how you created the command within the task sequence? Thanks.
