Hmm.... for a week or whatever.. my DVD-RAM Seems to have Problems.

When i try to Burn a DVD-RW 16x. It Gets stuck on 3%.
Yesterday it got stuck at 3% But today i could burn the same DVD.
After i burned the DVD ive tried to Burn another, and it did the same thing as yesterday.

It starts to make loud sounds from moving the DVD alot. And never ends.
I cant stop it unless i restart the pc.

Also, After i insert a DVD inside the DVD, In its Propreties it says:

Type: CD Drive
File system:CDFS

But i can see all the 4GB Contents from the Disk.
The Type is the same without no disktoo. but the File system is unknown.

Could it be that the DVDRAM Got Broken?
I did Opened it a few times, but that was a long time ago, I also Dropped Beer etc, and it has made it get out a bit harder.
