I don't know if it is OT or not. I have some questions: 1)In kernels of 2.4 series, the preempitve patch by Robert Love is compatible with the packet-cd patch? 2)The packet-cd patch will be included in the new 2.6 ? 3)It exist some utility for recover damaged cd-rw ? 4)It is possible to turn off the tons of error messages in console when the packet-cd find a damaged cd-rw or to send it to a log file? 5)It is possible to tell to stop the operations on damaged cd-rw even if the writes are not finished? Thanks in advance Carlo

I don't think so. I'm pretty sure this patch makes extensive changes to the kernel. OTOH, 2.6 will include the preempt patch, so you can apply the pktcdvd patch without any problems. Whether they will run harmoniously together is another thing entirely.
2)The packet-cd patch will be included in the new 2.6 ?
The feature freeze is in less than a week, so I doubt it.
3)It exist some utility for recover damaged cd-rw ?
Possibly. I'm not aware of any. You can try copying the CD contents from /dev/cdrom to a file and mounting it with as loopback device. If you can't copy the sector like this, chances are that your chances are slim, since AFAIK CD/DVD-ROM/R/RW devices do not have a low level access driver like the IDE task file which can be used to recover data from bad sectors on failed or partially failed disks (bad sector == CRC check failed) even though the data is probably corrupted. Of course, I could be wrong...
4)It is possible to turn off the tons of error messages in console when the packet-cd find a damaged cd-rw or to send it to a log file?
They're kernel messages. I think they're being logged anyhow, and if they're not, they should be. There's a way of changing the verbosity level of kernel messages with some entry /proc/sys, but I don't know what is is at the moment. Piping them to a logfile is unfortunately not an option.
5)It is possible to tell to stop the operations on damaged cd-rw even if the writes are not finished?
Yes. Press Ctrl + C to terminate the app. If that doesn't work, change to another VT and kill the offending program. Note that you have to unmount the CD before you can take it out of the drive, and pktcdvd will try to write to the disk if you've changed anything since you mounted it.
Thanks in advance

According to http://lists.suse.com/archives/packet-writing/2002-Oct/0046.html I thought it'd. -- 0@pervalidus.{net, {dyndns.}org}

Thanks a lot for help, but the problem for me is to force unmount, that seem taking too much time. Carlo
