Hello, I'm using cdrecord 2.0 from the SuSE 8.2 distribution. I can run successfully : mkisofs -R -o cdimage.raw burndata cdrecord -v -eject driveropts=burnfree dev=0,0,0 cdimage.raw Subsequently the burning seems to go well, fixation is done and the CD is ejected. But .... after reloading the CD and trying to mount it, I get <no medium found> !!! Moreover, it is also impossible to mount any other data CD anymore. After re-booting the system, I can mount data CD's again, and - surprise, surprise - the newly burned one can also be mounted, and contains the newly burned data perfectly. So the job was done allright by cdrecord. Jan Elders

The EIDE-SCSI emulation process is a horrid kludge. Not to berate the developers who did this, they didn't have much to work with. But this is mentioned in the xcdroast docs as something that can happen with a lot of burners. In theory, 2.6.x will be better as they dropped the SCSI emulation. Tom Allison

I'm using a QSI DVD/CDRW SBW-241 drive. Are you telling me that this is an unavoidable phenomenon with that drive which I will have to live with, i.e. no solution until (theoretically) 2.6.x is available ? Jan Elders

Not entirely sure. I got mine working last night just fine after a few weeks of problems. I think I disabled APIC (not ACPI) and that might have helped. I found the suggestion on the kernel.org mailing list. // CUT

The specific hardware shouldn't really enter into the problem as they almost all use ATAPI interfaces. It is this interface that the ide-scsi attaches to. I use lilo and have a config option to set hdc=ide-scsi. I think there is something similar you will need to do under grub. Do you?

I have had problems like this in the past, but not as many as you are describing here. In your position, I would comb through the congfiguration and see that everything was set up correctly. Also watch all the logging and -verbose settings you can get. That should help you find the root cause of the problem. Tom Allison

Well, I already had hdc=ide-scsi as config option and I just tried noapic as you suggested. The first burn session after that went all-right, with immediate mount possibility. So far so good, problem seemed to be gone. But the second and the third session had the same "old" problem again. So the noapic didn't really help. What puzzles me is why it occasionally goes well and frequently goes wrong ! This also was the case before I applied the 'noapic'. I would expect that it either works or it doesn't. By-the-way, under Bill Gates' software (Windows XP) all works fine, so the drive seems to be OK. Finally, I tried a cdrecord run with extended verbose (option -V), but the avalanche of information does not make much sense to me. Any more suggestions ?
