From: Kilian A. Foth on 13 Jan 2006 07:39 Since a few days I'm getting this weird error syndrome when trying to burn DVD-R discs: - my DVD writer can mount CDs, mount DVDs, and burn CD-R with no problem. - if I insert a blank DVD-R, the drive starts, but ultimately fails to recognize the disc (kernel says `cdrom: open failed' and burning programs return ENOMEDIUM, as if the drive were empty). (This is the same box of blank discs I was always using. I am assuming it is improbable that the first 12 were all OK and the last 13 are all bad, right?) - replacing the DVD writer with a totally different model did NOT cure this problem. However, rotating my optical drives so that the DVD writer is now the secondary master (rather than the secondary slave) DID cure it. As fas as I can see, the writer now performs exactly as desired. Apparently something about my computer apart from the drives is causing this. Can a bad IDE cable cause that sort of trouble, or do I have to assume (shudder) that my mainboard is going? -- No animal was harmed in the making of this post.

If the problem comes back, try a new cable. -- Do you mean that you not only want a wrong answer, but a certain wrong answer? -- Tobaben

Or maybe 13 is unlucky :) poly-p man
