    Disk Utility is worthless for the task. I found some chinese website that helps you do it on a PC, which I don't have.

    I just want to use this as a normal flash drive. Does anyone know how to reformat it on a mac?

    And what will you do if you manage to reformat the install flash drive and then happen to need to reinstall OSx? Flash drives are dirt cheap; buy one.

    Destroying your re-install disk is not a good idea.
