About a line 31 in cd-dvd.xml is sugested to use "hdparm" or "cdspeed" for slow down IDE-CDROMs and few lines after is something like there is no solution for SCSI drives. I've no experience with cdspeed but hdparm failing with IDE-CD if you use an IDE-SCSI emulation for cd writer. Best solution (after hard searching) is set a speed=<speed> option to mount command. This work better for me than hdparm even in native ATAPI with my writer, because this drive resets its speed setting with every cd exchange so it need run hdparm many times (boring and slow). Maybe it is a solution for SCSI drives too. I can't prove it myself, have no native SCSI. Next we should point reasonable speed settings because all drives do not support many speeds. For example my cd writer supports about 15 various speeds but my previous toshiba cd-rom could be set to 14x and 40x only, so if I set 24x it turn out as 40x (noisy) but after I set it <=14x , it slowed down. In my experience is 8x speed reasonable minimum and 24x reasonable maximum with noise under fans level. Any ideas? Jiri
