[solved] cdrecord not/very slow burning problem, corrupt

Lately I've been having problems with cdrecord. I tried updating it, and that did not help. I've tried it on both 2.6.11 and 2.6.17 kernels. I have scsi cdrom and such enabled in both and ide-scsi emulation turned on in grub. Neither seem to support scsi emulation. It has worked before with /dev/cdroms/cdrom0 or /dev/dvd. No matter what I set the speed to, it seems to burn at about 1X, or it may call it 4X. Either way, it let a normal sized iso burn for about 5 hours once and it didn't finish. I can use graveman as a frontend and don't seem to have that problem. It still burns slow, but it finishes. Unfortunately, the resulting cd does not work. I've tried downloading the ISOs again to make sure it wasn't corrupted. Neither ftp nor torrent downloads of GoboLinux work, for instance. growisofs burns dvds just fine. I can post whatever info might be useful. Thanks, and I hope this is the right forum.

You do not use ide-scsi in kernel 2.6 for burning anymore. Disable it. Have you already tried without it?

I took it out and it still doesn't work. A test run goes at full speed.

- become root
- check for DMA
- don't use ide-scsi on current kernels
- post used cdrecord command
- post complete output of cdrecord command
- try another iso
- try another media

- become root - always for burning
- check for DMA - check
- don't use ide-scsi on current kernels - check
- post used cdrecord command - # cdrecord dev=/dev/dvd driveropts=burnfree speed=8 GoboLinux-012-i686.iso
- post complete output of cdrecord command - will do next time I burn, but it claims successful with whatever speed I choose if I let it sit for like an hour
- try another iso - tried GoboLinux and ReactOS
- try another media - check

I thought I should also add that cdrecord doesn't work in Slackware either.

Kernel 2.4.20 with an older version of cdrecord burns the disk successfully with scsi emulation and speed=16 driveropts=burnfree
Any ideas on how to update my firmware are welcome. It's a Plextor 716A, and I can't get pxupdate to work.

It worked or got pretty close with k3b under a 2.6 kernel. It wasn't entirely successful, but I think some of that was due to the crappy media. I did not try it with the good media that I used for the successful 2.4 cdrecord burn.

I upgraded the firmware, and I still get errors. It burns fine in my Plextor CD burner.

The problem isn't really solved, but I determined that the problem isn't the drive or the kernel. It works properly in kernel 2.4 and doesn't in 2.6, and it would probably work correctly in Windows. The media are pretty crappy, though. With a 2.6 kernel, the drive can't handle media that crappy, while my cd burner that normally operates at slower speeds can. I found a non-shitty (only 16x, though) disk, and the burn went fine.

This is a little late, but I just had a bad experience with a Plextor PX-716A which I believe is the model you have. It had trouble recognizing some store-bought media (that nothing else in my possession has any trouble reading, including an old DVD player attached to my TV).

In windows (I tried everything) it would give "unrecognized format" errors and in Linux (2.6.17-r5) it would give:
