[NTLUG:Discuss] erasing ISO image from memory stick

[Ed Leach]

I have an Ativa memory stick. When I plug it into the USB port it mounts 
a free memory partition to /dev/sdb1. But it also mounts an ISO9660 
image to /dev/scd0.

How do I get rid of the ISO image and make the space available as free 
memory? (I have nothing on the memory stick, so I can reformat the whole 
thing.)

Thanks,

Ed
