I meant the computer I am writing this email on, not the one that won't
boot the usb.

Automount on the computer I was examining the usb stick not the one that

partitions on the usb.

I am willing to try this but after reading the fdisk man page I am not
sure how to do it. Won't fdisk corrupt the files in sdb1 if changes are

Should I just power off or is there a way to gracefully exit the
