I have LG Combo Drive(GCC-4521B107(ew)). I download firmware from the LG site and start installation. But during the installation power lost. After that i restart my pc but it dosen't start. So I remove Combo Drive and restart and it starts. Now whenever i connect Combo Drive than i cant start my pc.i hav to remove it. So i think firmware may be damage. Can i recover it Or I have to buy another Drive.
