Last week I bought myself a DVD burner and don't seem to get it working right (argh). As far as I know, I tried all possible connection possibilities and I am close to throwing the stuff out of the window...
For the record: I can burn dvd's, but when checking it with a md5sum it fails. I have downloaded the FC3 dvd iso file and after downloading, the md5sum checks out. When I burn the iso file (with K3B) the verify option fails afterwards. If I burn the file with Gnome and do a manual md5sum on the dvd, it gives a complete different number (everytime I burn the iso file, I get another value)... I have been using a new Philips RW disc, also tried it on a regular (no RW) Philips disc... I also updated the firmware of the burner, still no improvement.
I have a 80 gb harddisk (Western Digital WD800JB), a LG dvdrom (GDR-8163B) and a Plextor DVD burner (PX-712A). I also have a additional ATA100 ide controler card (Ultra100 TX2) lying around, together with plenty IDE cables (40 pins and 80 pins). My P4T-F motherboard has one blue coloured and one black coloured IDE connector (both should be ATA100 capable, but the manual advises ATA100 on the blue one and no-ATA100 on the black ide connector).
Can someone please tell me what I forgot or missed here? What is the best way to connect these components... should the burner be alone on a ide channel or can it combined??
Regards, Patrick

Have you tried booting with the "ide=nodma" kernel option?
If I boot my machine with DMA enabled I can't read past precisely 201906176 bytes on media in either of my DVD drives. (Incidentally, this seems to be the point where the drive switches to high speed.) I can write DVD/CD media without any error. When I disable DMA the media that I had previously written checks out fine.
In my case it does not occur if I use the ide-scsi driver with the device. (Although ide-scsi has some other strange side effects such as not ejecting media.) Also, I can enable DMA once the system is up and running without any ill effects. I added a "hdparm -d1 /dev/hdX" line for each IDE device to /etc/rc.local (where X is a-h). I can only guess that something occurs during init that scrambles either my IDE controller or DVD drives if DMA is enabled.

Patrick,
In the off chance that k3b's md5sum method has some kind of problem, have you tried booting the DVD and running the media check to verify the integrity? I seem to remember having a similar problem, but the media check passed.
