I ran into an interesting issue this week trying to image a Surface Pro 2018 with a 1TB hard drive. Some people may ask why I was trying to image this type of device, but that’s a conversation for another day. This device presented a problem because of how the drive is configured.
This device actually has two 512GB drives that are presented as one 1TB disk through a RAID configuration. Then the drive is mounted, it mounts as disk 2, instead of the normal disk 0, so my OSD was failing. It was a pretty easy fix, but it took me some time to get there.
Partition Disk
My task sequence was failing on the partition disk step, as ConfigMgr did not have a drive 0 to target.
For these models, disk 2 needs to be targeted.
So, how do we do this and not have to have a special sequence for this model? I added a second partition disk step with the same drive configuration and used conditions on the steps. Here are the two WMI queries I added (both are in the standard root\cimv2 namespace):
SELECT * FROM Win32_ComputerSystemProduct WHERE name = “Surface Pro”
SELECT * FROM Win32_DiskDrive WHERE Index = 2 AND InterfaceType = “SCSI”
This query targets just Surface Pro’s (older Surface Pros say something like “Surface Pro 4”) and those with a disk mounted at position 2 that also has an interface as SCSI. Adding the InterfaceType will prevent this step from executing if it sees a USB drive at disk 2. I think this should be sufficient targeting for a mistake not to be made. The only issue I can foresee is if Microsoft changes the disk configuration in a future model that could throw this off.
So, on your regular partition disk step, set the conditions like this:
Note that I left the default configuration and added an If statement with it’s condition to none.
On the new partition disk step that targets disk 0, I did the exact opposite:
Here, the If statement is set to all, so that this step will only run if both conditions are true.
After adding this configuration, your task sequence should successfully deploy on a Surface Pro 2018 with a 1Tb drive.
