Terrible performance while burning CDS

I get extremely bad performance when I burn CDS. This happens using both cdrdao and cdrecord.

The symptoms (this gets worse as I increase burn speed) are:

- fairly slow write, if I do not have burnproof buffering on, my writes always fail

- every few seconds (more frequent if I am burning at a higher speed) my box becomes completely unresponsive, it even loses characters while I am typing etc

- if I put a CD with or WITHOUT data on it in my tray, one of 2 things happens.
....A) the green light comes on, goes right off, and I can mount/use the CD perfectly fine
....B) the green light stays on for a very long time, eventually turns off, and my box does not recognize a CD is in the drive
if B happens, I fix this by opening and closing the drive tray. This is COMPLETELY random it seems. Sometimes it will be fine for several cds at a time and then hokey for a while.

I do not know what I should be checking, here is all the data that I see relevant. Please, if you need me to check other things let me know - this problem has plagued me for over a year now and I am sick and tired of it (and nobody on irc seems to have any suggestions, and I can't seem to find any truly similar problems on google)

You have your CD drive on hdd and nothing on hdc?
Try to switch your CD drive to Master instead of Slave, and look if that helps.

I have also a LITEON CD Burner and compared to my new DVD Burner it shows absolutly weak performance. I thougt this is because the CD Burner is the slave of my first IDE controler together with my harddisk. But maybe these Drives ar just crap :roll:

. The DVD Burner works flawlessly (also a slave device). Maybe I will look for a firmware update.

*** edit
I thought that switching to Master did nothing, but I was not correct. When burning normal data cds with (cdrecord -v speed=12 dev=0,0,0 driveropts=burnproof /path/to/image.iso) everything works PERFECTLY. This did not used to be the case, so thank you for a solution that at least fixed that problem.

When I burn using cdrdao, problems still persist. Additionally, I still have the issue that when I put a cd in the drive it frequently will just 'spin' and not read it.

Perhaps it is a problem with the drive itself (more accurately with the linux support existing for it). I'm sure other people use this drive; can anybody share their positive or negative experience with it, so I can get some clues?

Still looking for suggestions,
Robert

bumping b/c I thought my edit would, but it didn't
