How do I re-format a usb drive that i used to make a bootable ubuntu drive?

No, I haven’t Created the partition table yet or formatted it.

I will post my results, when I get a chance.

If /dev/sdc is the USB stick then you can zero it out with:

sudo dd if=/dev/zero of=/dev/sdc bs=1M

You should then be able to create a new file system in Windows etc. Be sure to double double check that you are working with the right device, otherwise ‘dd’ can stand for ‘data destroyer’

The simplest solution to your problems is to simply use gparted or a similar tool to create a new partition table. Gparted is on any Ubuntu live usb and if you have the correct drive selected, click on the Device tab at the top and select an option, gpt would be best. Once you do this you can create partitions and filesystems on the partitions. This has been suggested in posts above but you still have not done it per your last post.

Thanks for the help everyone.

I was finally able to get it formatted.

Zero’d the drive , as suggested, and then was able to format it without issue.
