MDT (v.8450) and Disk Allocation Unit Size RRS feed

  • Question

  • I have MDT version 8450 setup and operational for deploying workstations for us (a small variety of Dell laptops and desktops) as well as now to deploy Windows 2012 R2 to our VMware environment. I do have a bit of a problem, however. We are on a hyperconveged solution which requires the C:\ drive to have an 8k allocation unit for the deduplication engine that is used. It would appear that the MDT task sequence has no means to alter this--at least not from the GUI. I'd rather not modify one of the default scripts if possible as well.

    I did run into this and tried it, but it just failed for me:

    Does anyone have any other suggestions for a way to handle this--preferably just with a task sequence item and a script at most (w/o modifying a default script so as not to affect deployments to our workstations)? Here is the chunk of error form the smsts.log file:
