I managed to test a bunch of USBs during a gig. 2 of the USBs i formatted with "MiniTool Partition Wizard" and 3 of them with "HP USB Disk Storage Format Tool"
The goto tool for me always was "MiniTool Partition Wizard". Guess what, al the USBs formatted with that tool failed. The USBs formatted with "HP USB Disk Storage Format Tool" worked perfectly.
