SCCM – Create Stand Alone Media using larger capacity memory sticks
If you need to create standalone media for any of your task sequences within SCCM, you may find that you have to use a large capacity memory stick.
I have found that when I’ve tried to use a 64GB memory stick or above, the Create Stand Alone Media process always fails. So to get round this, there are two ways; do not use memory sticks larger than 32GB or using diskpart, create primary partition of 32GB.
Run CMD as an administrator on a machine with the Configuration Manager Console installed:
Then type diskpart to enter the DiskPart utility:
Then type in list disk to list all of your available disks:
As you can see from the above screenshot, my 64GB (although it says 57GB..) USB stick is disk 7. Once you have identified your USB stick, type in select disk # (# = the disk number, in this case 7):
Then you want to completely clean this disk, so type in clean (please note that this will completely wipe your memory stick so make sure you want to do this before this step!):
