Yes, that seemed to be the problem. Thanks a lot for your help!

I'm using an Acer Aspire 5742G laptop and the DVD ROM seems to be PIONEER. But I don't really know how to find out what chipset the controller uses. How do I do that? Oh, and on acer.com there are no drivers for the DVD ROM and when I update the driver it says that the device is up to date. If you need more info please ask, cause I really want to solve this extremely frustrating problem. Thanks

It's not just with ImgBurn that I can't erase a disc, but with windows 7's "erase disk" option and nero also. Pretty much, everything I have tried did not work.
