DISK0 not found when you deploy Windows on Surface Pro Model 1796 or Surface Laptop

Applies to: Surface Laptop (1st Gen)Surface Pro (5th Gen)

Symptom


When you deploy Windows on a Surface Pro Model 1796 or Surface Laptop 1TB device, you may encounter errors or other issues that concern locating the DISK0. For example, if you are using Microsoft Deployment Toolkit (MDT), the following error is logged in the bdd.log file:

Cause


This issue occurs because Surface Pro Model 1796 and Surface Laptop 1TB devices use Storage Spaces technology to combine two 512-GB drives into a single drive. Storage spaces drives are virtual, so they are listed after physical drives. Due to this configuration, you have to target Disk2 or Disk3 instead of Disk0, depending on the device and whether an SD card is present.

Resolution


To work around this issue, change the deployment tool to target the correct drive according to the following information:
  • Surface Laptop: Disk2
  • Surface Pro Model 1796: Disk2
  • Surface Pro Model 1796 with SD card inserted: Disk3
For example, if you are using Microsoft Deployment Toolkit, you can change your task sequence "Format and Partition Disk (UEFI)" step to change Disk Number to 2 or 3.

Note This means that Microsoft Deployment Task Sequence is specific to these kinds of devices and cannot be used with other devices.
