I've noticed that once alcohol 120% is installed on my laptop it creates a virtual DVD drive (in my case Drive E that appears on "My Computer". Unfortunately for whatever reason this seems to interfere with my external DVD reader/writer and whenever I turn it on via USB 2.0 I get an immediate shutdown. This is weird because my external DVD drive is Drive G:. So whenever I use alcohol I have to install and uninstall once my tasks are done in order to get my external DVD device to function, be acknowledge by my computer and not cause immediate shutdown. Is there any way to get around this so I can keep the alcohol program installed on my computer and also use my external DVD device? Thanks.
