During OS deployment, format the C drive only

When OS deployment is done on systems, sometimes it's needed to wipe just the C drive and keep existing data on the D drive. When using a default task sequence in SCCM/ConfigMgr or MDT all data is wiped. This because exiting partitions will be deleted and created again. In this blogpost I explain what to do in this situation.

Just create a default task sequence for OS deployment first. Just edit it after creation and remove any “Format and Partition Disk” step. You can't use this step without wiping the disk at all. In the "Apply Operating System Image" step, make the following modifications before deployment: Set the destination to a specific Disk 0 and Partition 1 (for example), so it's fixed after that.


That way only the partition configured will be used. Other partitions or disks will be saved this way! During the "Apply Operating System Image" step, the configured Disk and Partition will be formatted first before installation. Job completed!

      Yes, you can also use a variable (OSDisk) during disk format, and use that one on the Apply OS step.

    I deleted “Format and Partition Disk” and changed the settings in "Apply Operating System Image" but while running TS it gets failed & gives error code 0x80070070.

    I believe it is not getting partition to install the OS. what could be the issue.

      Just make sure to put the OS image on the right partition. Press F8 and check diskpart.

    Probably the "Given variable name" isn't recognized. Use the "Specific disk and partition" instead.

    My company is using workstations where there are 2 physicals HDDs.

    Disk 0 is SYSTEM disk (SSD)
    Disk 1 i DATA disk (HDD)

    By default, I think MDT is only deleting disk 0, am I right? We don't use partitions (DATA & SYSTEM) on the same disk. Do I have to be afraid on have my DATA disk erase?
