I had 8 thumbdrives I needed to format and set as bootable today. The nice thing about diskpart command-line utility is that you can put all your diskpart commands in a plain text file and call that file using the /s command-line switch.
Please note: select disk 1 is specific to my environment. Please run diskpart manually and issue list disk to determine which USB drives.
diskprep.txt
This is the file which contains my diskpart commands.
select disk 1 clean create partition primary select partition format fs=ntfs label=BOOT quick active assign
PrepDisk.bat
This is the batch file I used.
@echo off diskpart /s diskprep.txt pause exit
