"Have had my computer for nearly two years and just recently have been getting this message
Optical Drive Device Locked Acer e lock activated.
Feeling a bit of a failure as I don`t know how to get rid of this or sort it out and now my cd is not working ( access denied).
You commented that you had a workaround or fix for this. I am trying to resolve this same problem on my niece's computer and I would appreciate any help that you could offer.
