How can I format a USB stick that's falsely marked as read-only? I was trying to create a bootable disk with Windows on it through bootcamp, but something went wrong during the installation. Now I have a read-only USB stick with corrupt files I'd like to fix. My USB stick doesn't have a read-only feature. Is there anything  I can do to force a reformat?
Try to partition the disk first.

If fails then by using Vendor and Product IDs of you flash drive find manufacturers' utility to perform low-level format. You will need Windows for that.
