I've spent about 20 hours on this with both a 3G and 4G DVD-RAM drive. I finally came to a common denominator, the kernel. Kernel 2.4.20+ is causing this _exact_ issue with ATA reliability. And even when I _do_ get a successful record, I typically get errors. The "proof is in the pudding" when I use a DVD-RAM drive and packet write (rewrite) DVD-RAM discs that does "verify after write" -- I get errors and rewrites all over the place. I've only followed the ATA development on the kernel from an "outside" perspective, but I believe Hendrick's ATA work is no longer in the 2.4.20+. Or they did something else. And it shows. I've played with a number of stock and Red Hat kernels and this is the only thing I can find that is common in all situations/systems/drives. I've gone back to a Red Hat 2.4.19 kernel on some of my systems, but I also use NFS. The Linux NFS client is far better in 2.4.20+ kernels. So I'm considering going way back to a Red Hat 2.4.9 kernel instead (before all the VM screwing). -- Bryan J. Smith, E.I.
