Ugh, yeah, that was it. I had just forgot to unmount it and I hadn't used the program in a while, so I just forgot about it. Of course it was something easy. What was I doing mounting it anyway? I don't even remember.

...and after a restart, the mysterious drive has resurrected itself

One more thing, I've burned and deleted other ISO files, but this one is the only one that I can't get rid of.

I tried searching through the forums but I didn't find any other threads with this topic, so if this has been posted before, my apologies. Anyway, every time I try and delete the ISO, I get the annoying "it is being used by another person or program" message. No burning or video programs are in use that should come in conflict with the file, but I still can't get rid of it. One curious thing, the ISO somehow created its own CD/DVD-ROM drive in my My Computer menus, with the ISO filename permanently imbedded there. I had to go into my system drivers and disable and remove the superfluous drive, but the ISO file still won't delete. If I knew which process the file was using, I would just end that, but I don't want to go ending random processes without knowing what they do. I would appreciate any help. Thank you.
