Hi Thomas, Hi Bill, Thanks for the suggestions. I'm still unable to burn DVD+RW's with growisofs and suspect a bug. > > Burned or not burned? dvd+rw-mediainfo can't decide > > Your observations indicate that the drive is > not able to recognize the media's formatting > and data content although it did not report > an error during the write run. > The media info after writing is explainable > if the drive cached the formatting info in its > internal memory until the media got ejected. Yes, it looks like a drive cache issue. I'll just eject and re-load to check from now on. > It may be that the media shows up as formatted > and readable in a different drive. Nope. Each time they come up as blank on different drives even though they are burned without growisofs returning an error. > For the drive in question you should get media > from a different manufacturer. I'm using TDK bought from a major supermarket, not a no-name brand. TDK DVD-RW's burn fine, but TDK DVD+RW's come up empty after burning. I have tried two different burners from different manufacturers, in each case the devices support DVD+RW according to the manufacturers. I have tried on two different PCs, with two different releases of ubuntu (8.04 and 8.10). I have reformatted the media with dvd+rw-format /dev/dvd but after burning the DVD+RW's are still empty. Possibilities I'm considering are that I've got a bad batch of media and that growisofs is buggy. If burning fails, growisofs should report it, but some users have found that it doesn't always report problems: https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/59506 Is there a way of burning a dvd that circumvents growisofs? I don't have Windows which would have been handy to check. Cheers, Parker Find a cure at MSN NZ Money Got a 2008 financial hangover? |
