I apologise if this has been posted before but I cannot find a solution for this anywhere.
I have the SOSW-852S dvd-rw model installed in my laptop. It was working fine until a few months ago when it completely dissapeared from my computer, device manager and BIOS. The strange thing is that lately it has been re-appearing one boot and then dissapearing the next.
I have no idea how to fix this, I have deleted the upperfilter and lowerfilter from the registry and I have removed various pieces of software such as nero and daemon.
Any help is appreciated, thanks.
