I have crashed my CD/DVD burners drawer/tongue by making a false move with my knee. I broke it out of my PC.
No plastic was broken, and i have inserted it again into the slot, where it belongs to.
Now, when i open the explorer, i have an unknown CD/DVD device, named german language installation of win7:
BD-ROM-Laufwerk (F:)
and also my "normal" CD/DVD writer/reader named: DVD-RW-Laufwerk (G:), as usual.
But if i insert a CD/DVD or just try to close the drawer, it just rejects it after 2 seconds and opens again.
