Do IDE cable that are cable select make a difference?
I have a M848AL U Rev. 2.1 motherboard with an AMD Athlon XP CPU. I assume my IDE ribbon cables are cable select due to black, End (master) gray (mid connector) and blue (mother B) colors of the connectors. In the documentation of the mother board there is absolutely no mention of Cable select. Rather it says to jump as master or slave. I have a DVD model AW-Q170A-B2 that will show all disc types but DVD doubled layered. It burns fine but I have not had the occasion to burn a DVD doubled layered. I realized the problem when I tried to install a Linux double layered installer DVD. It started the installation then errored as if it could not find the files it needed I assume on the second layer of the DVD.
It shows correctly as the master on the secondary IDE bus in the BIOS. The only thing so far I have come up with is the ribbon cables I thought that they would be backwards compatible. Could this be the problem? |

If the drive could not be seen or accessed, I'd start looking at jumpers. If the drive works for at least one test CD, then the cabling and jumpers are fine. Either Google the optical drive model, and verify it does DL. Or get a copy of the free Nero utility that lists out optical drive capabilities. It's a Windows utility unfortunately - which is why you use Google, enter the drive model number as a search term, and try to find a picture of someone running the Nero tool against that particular optical drive. There are two review sites, that review new optical drives, and sometimes they have pictures of that screen. The tool is called Nero InfoTool, and it was actually written by a third-party (an individual) and bundled with Nero. I think Nero offers it (free) from their ftp server, if you can figure out where it is stored. But it's a Windows only utility. In this example photo, the two clusters of tick boxes, one set is for disc read capability, the other set for disk write capability. And in that example, the DVD+R DL read box is not ticked. Yet it can write to DVD+R DL. Which is surely strange. http://www.softportal.com/scr/2549/n...tool-mid-1.gif That tool has been around for a while, and the appearance of the GUI has changed slightly over the years. When I pick a sample photo of it, I usually pick a picture I "like", rather than picking the latest copy, which might be more ugly looking. I expect Linux has some way to list optical drive capabilities as well, but I haven't a clue where I'd start looking for that. Usually the single page spec for the drive will also list all of those, but you can never find a copy of that when you need one. And the Nero tool, reads it right out of the drive. So somehow, the drive reports that stuff, like what it can read or write. Paul |

Not one necessarily to be ruled out. Since early drive/cable dependency devices, I'm always careful that, in the event of anomalies, there's always extra known good cables available to re-check myself. Also test for inter-device incompatibility interactions by removing them, one by one, to test in singularity if need be. A non-CS ribbon is getting pretty rare, and follow thru with jumpers to the CS scheme (other jumper logical states may be tested apart from that, although I'd find that dimly counter-intuitive if a jumper worked in any state contrary to its placement on the cable). |

I didn't read the entire post. He's burning optical media but trying to blame a cable when doing double-layered burns (whatever the hell DL is). |

Inside the drive, a single laser is refocused when switching between layers, accounting for a slight delay when moving from the top to the bottom layer. DVD+R DL discs use a single refocusable laser to write both layers" There is a chart with four different entries, for optical types here. http://en.wikipedia.org/wiki/DVD#Dual-layer_recording CD = 780nm DVD = 650nm --- red BluRay = 405nm --- blue A backward compatible DVD drive has two lasers. A BluRay could have three lasers (i.e. the ones that claim to play all media) A CD laser used to cost a buck or so. Don't know about the others. Each laser is driven by a laser driver chip. The power level is programmable, both during read and write (so read power level isn't the same as write, and when writing, the write scheme can vary with the media type). If a Dual Layer operation commences, that means the drive claimed it was DL, and the operation is going ahead. If it dies half way through, then the focus could be broken (or out of focus for one layer only). While reading one layer takes more laser power than reading the other, the laser would need even more power for writing. If the lasers had a back-facet monitor, the actual power level could be observed, and the drive would be able to tell you when the laser was dead. But then the laser wouldn't be $1, if they added a back facet monitor. It would probably be $1.50 :-) So if the laser isn't doing well, the drive may not be clever enough to "turn it up". In addition to a laser power or focus issue, there is the firmware to consider. A failure could potentially be caused by a very early firmware. When I buy an optioal drive (not that often), the first thing I do is flash upgrade the drive. As that adds more media tags. When a media tag is recognized, that gives the drive more useful information when it is called on to write something. While in the past, a buffer underrun would have cooked (made a coaster) out of the media, current drives have sufficient underrun protection, that a slow computer is no longer a liability when writing discs. At one time, if a user foolishly connected a fast optical drive, to a USB 1.1 port, it might have been possible to data starve the drive. But drives now, seen to have an un-ending list of underrun protection schemes (each invented to get around patent or trademark issues). So I doubt that's a problem any more. I remember the first time I tried to burn a DL disc, I noticed the status LED on my drive, the LED would only "blip" once in a while. Turned out, the USB2 driver for my chipset, had somehow disappeared, and the damn drive was running USB 1.1 rates. After reinstalling my chipset drivers, the LED would stay on steady, on my next burn attempt :-) Now, that's something I don't check very often (Device Manager). I simply assume Windows isn't going to pull the rug out from underneath me when I'm not looking :-) You're on an IDE cable, and the IDE cable has a decent bandwidth. The only time it wouldn't, is if Windows switches to PIO mode on its own. http://support.microsoft.com/default...b;en-us;817472 I'm thinking your problem is mechanical (focus), but that's just a guess. If there were any more "interesting" symptoms, maybe it would narrow down the issue. Paul |
