I have an odd issue with the Surface Pro 3. I am using MDT/WDS to capture and deploy images to our machines. I have been able to capture an image using LiteTouch with no issue, and am able to install a fresh Win10 OS using MST. When I attempt to deploy my custom image, it hangs on the step “Format and Partition Disk (UEFI)”. Afterwards, I open CMD and check the disks under dispart, and the disk is missing.
If I reboot and go into WinPE then exit to command prompt, and attempt to format a partition manually, the disk will drop and not be available until I reboot. Has anyone seen this behavior?
