Preparing a USB key for installation

Hi Chaps,
First post. Appologies in advance if this is the wrong list. This concerns installation of Fedora based distros from a USB key. I've read the guides that say one should run;
dd if=diskboot.img of=/dev/sda
This works fine and I've been able to install OS using this method. However the partition table that this command creates is rather unusable for any thing other than installations. [output of fdisk -l listed below].
It seems as if the USB key is partitioned in such a way that all of the nth scsi device is used. It would be nice to be able mount the USB key in order to say, out an iso image on it. Bit of a waste of a 1GB USB key in that I do have the sapce for diskboot.img *and* an iso image.
# here comes output of fdisk -l

This doesn't look like a partition table
Probably you selected the wrong device.
