- can anybody reproduce what my experience?
- can anybody tell me what happend here, and whom to blame?
I got my NEC ND-3540A DVD burner today. Popped into the system, upgraded the firmware from cdfreaks and then burned Knoppix 4.01 on a Verbatiam DVD+R at 8x speed. It took about 8 minutes to burn. The burned DVD+R works perfectly in my system.

How did you get the DVD ISO file? Did you use bitttorrent or did you download from a web or ftp mirror? If you did not use bitttorrent, have you checked either the MD5 or the SHA1 checksums & made sure the DVD ISO file is perfect & not corrupt? You might be wondering: "Why would you want to prove that it is a perfect download or that the DVD was burned perfectly?" The answer is: If the ISO that was downloaded has a small error, or if the DVD was burned on bad media, or if the DVD was burned too fast, it will result in crashes, lockups, and strange errors. We have seen this happen consistenly for years.

These types of questions are all documented at the Downloading FAQ http://www.knoppix.net/wiki/Downloading_FAQ. So how can we help you? Perhaps you have already done them but you must do some simple tests to rule out the chances that the DVD or ISO download is the cause of the problems. If you choose not to do those tests, then there is no way we can help you determine the cause of the problems.
