can't force low speeds when burning cd's

bennethos · 09-15-2010, 04:06 AM

Hi,

No matter which soft I use I can't seem to force slower speeds, it always burns at 10 to 12 speed.

I tried cdrecord, gnomebaker (speeds are not grayed out, I can choose whatever I want but it always burns at max speed).

It's a SATA burner in a portable.

raven:/usr/src/linux-source-2.6.32#wodim -scanbus
scsibus1:
1,0,0 100) 'HL-DT-ST' 'DVDRAM GSA-T50L ' 'SC04' Removable CD-ROM
1,1,0 101) *
1,2,0 102) *
1,3,0 103) *
1,4,0 104) *
1,5,0 105) *
1,6,0 106) *
1,7,0 107) *

/etc/wodim.conf CD speed is commented so it defaults to fastest speed, if I put 0, 1 or 2 in it. Same problem...

any idea's ?

thx

Hi,

Did you try to use cdrecord's speed option?

From the man page:

Quote:

speed=#
Set the speed factor of the writing process to #. # is an inte-
ger, representing a multiple of the audio speed. This is about
150 KB/s for CD-ROM, about 172 KB/s for CD-Audio and about
1385 kB/s for DVD media. If no speed option is present,
cdrecord will try to get a drive specific speed value from the
file /etc/default/cdrecord and if it cannot find one, it will
try to get the speed value from the CDR_SPEED environment and
later from the CDR_SPEED= entry in /etc/default/cdrecord. If no
speed value could be found, cdrecord uses a drive specific
default speed. The default for all new (MMC compliant) drives
is to use the maximum supported by the drive. If you use
speed=0 with a MMC compliant drive, cdrecord will switch to the
lowest possible speed for drive and medium. If you are using an
old (non MMC) drive that has problems with speed=2 or speed=4,
you should try speed=0.

Something like this maybe: cdrecord -v -eject speed=8 driveropts=burnfree dev=1,0,0 gracetime=3 -pad <path/file>

Hope this helps.
