HI. I had an interesting experience with my 112D having CD-R burning problems a few days ago.
I had several CD-Rs to burn and my DVR 112D suddenly started playing up. Basically it coastered 3 out of 4 CD-R’s, even though I dropped the burn speed to 16x after the first coaster. I was using media that has also been up til now flawless and after the first two coasters I changed media type (and rebooted computer) but still got another coaster immediately on the next burn.
Essentially the burns would proceed normally up to about 5% or 10% and then fail, resulting in a coaster. Unfortunately I didn’t save the log files because I was busy at the time and quite frustrated with the untimely failure. I didn’t have time to be messed about with this so I didn’t investigate very thoroughly. I hastily swapped the 112D for my old LG H10 and got back to work (and had no further problems).
The Drive is Feb2007 and the firmware is 1.21 official (never been crossflashed), software is Nero6 (22.214.171.124), UDMA-4 is working correctly, no Nvidia drivers involved and up until that day it had been burning flawlessly.
Well here’s the interesting part of the story. I had given up the drive for dead but today I put it back into my older (backup) computer just for a final test. Hmmm, now it’s buring CD-R’s again but I don’t know what’s changed. Both computer are 100% stable, and the original computer is working fine with the LG drive, so I donâ€™t see how it’s a computer problem. One thing that’s slightly different is that this backup computer is running Nero6 Express 126.96.36.199 (the main computer had Nero6 full 188.8.131.52). When I get time I might try the 112D back in my main computer and update the burning software to the same version of Nero express.
Of course the other thing that it might be is just plain old dumb luck. Three coasters out of 4 attempts is not really that conclusive. I might have just been really unlucky with the media that day (or really lucky with the 4 or 5 burns and no coasters that I’ve just made with the 112D now in the backup computer). Like I said before I would have liked to investigate it more but was too busy and frustrated with it letting me down to waste any more time or media on it at the time. Hopefully I’ll get some answers when I get the time to test it again in the original computer.
BTW. Note that I’m onlt talking about CD-R’s here, the drive has never yet failed on any DVD+/-R burns.
