Prevent if from auto mounting. udisks seems to like it. Manually unmount it, if you must.

You're not supposed to mount it. You want to remove the partitions. Unmount it entirely, prevent udisks from mounting it (remove udisks, if necessary) and use gparted or parted. Create a new partition table to get rid of the MBR.

Re: formating a live usb

*web link*

remount
    Attempt to remount an already-mounted filesystem. This is commonly used to change the mount flags for a filesystem, especially to make a readonly filesystem writeable. It does not change device or mount point.

    The remount functionality follows the standard way how the mount command works with options from fstab. It means the mount command doesn't read fstab (or mtab) only when a device and dir are fully specified.

    mount -o remount,rw /dev/foo /dir

    After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command.

    mount -o remount,rw /dir

    After this call mount reads fstab (or mtab) and merges these options with options from command line ( -o ).

So if your system/flash drive/disk/whatever is mounted as read only and/or possibly write protected, remount it as read write.

Re: formating a live usb

Whatever you're trying to do, you don't want to use FAT in anything below FAT32. vfat it is.
