Some USB keys have been found to have various partition table set-ups that the USB software will not work with. You can use Windows Diskpart to re-format a USB key and re-partition it.

  • Open a Command Window (cmd)
  • Enter diskpart
  • Enter list disk (it is important you KNOW which disk is the USB key you are formatting)
  • Enter select disk x where x is your USB key
  • Enter clean
  • Enter create part primary
  • Enter select part 1
  • Enter active
  • Enter format fs=fat32 label="Tabernus" (Label is optional - ensures USB key is labelled as Tabernus in Explorer etc)

The process can take some time, but the USB is now operational for Tabernus USB Erase.
