I bought ASUS DRW-1814BL recently. However, new revisions of it are faulty and fail on reading CDs and burning light scribe discs. That means that you cannot install even Windows XP on it since the disc/CD won't even boot. It reads DVDs fine.
Apparently, this problem is widespread and ASUS's DRW-1814BL forum is full of people complaining about this drive. The new firmware v1.14 is available but it is reportedly making no improvement as far as this situation is concerned with this drive.
The reason for this thread is a general notification for people to avoid buying this DVDRW drive, especially the recent iterations of it. I have an older DRW-1814BL (white front cover) which works fine. This one (black front cover) is faulty. Avoid buying it like it is the plague.
If anyone has had a different experience, please do tell. I would be interested in knowing about it.
