Optiarc ad-7530a detect no CD/DVD

Hallo together,

my english is not very good but i try my Best.

I Have a Problem with my DVD-Burner optiarc ad-7530a.

My OS ist XP and i have the Notebook Acer Aspire 5570.

The Drive cant detect any CD or DVD. If i insert a DVD/CD it says there is no DVD/CD inside. Also if I reboot my Notebook and there is e.g. an Win XP inside it didnt boot from the DVD-Drive.

I try try to delete the Upper and LowerFilters but this didnt help.

Do you think my Drive i broken? Or could it be a software Problem?

Should i try to update the Firmware? Where can i get the newest Firmware for this Drive.

Thank you
