Deleting Volume

[dedukes]

Hi. My backup program created a backup volume on the hard drive it is supposed to backup, doubling my harddrive's size. It did this before (why, I'm not sure, but I deal with that issue later).

I found the file (Volume) with WhatSize. but WhatSize freezes when I try to move it to the trash through WhatSize. I can't see the volume in Finder. any ideas on how to delete this volume?

Thanks.
