cdrecord and Sony IDE Drives

cdrecord and Sony IDE Drives

[Martin McCormick]

	I upgraded to Linux3.0 this Summer and my ability to
record CD's using SCSI emulation died on two different systems.
On one system, I finally got it working with some help, but it
does work again like it should.  It turns out that you must
enable SCSI emulation in your kernel which is no big surprise.
You also must enable CDROM support even though your CDRW drive is
an IDE drive, and you must also enable generic SCSI support.

	That fixed things for that system.

	My work station at my job location seems very similar in
that it is a Dell Dimension series system only slightly newer
than the one I got back to good health again.  Its IDE drive is a
Sony drive but is otherwise a normal IDE device.  After I did the
same three things to that system, it showed all the correct test
results one can look for.  If, for example, you type

cat /proc/scsi/scsi, you will get a listing of all the SCSI
devices you have.  I see the CDRW drive and it also shows up
properly in a second test one can run that will make your system
output a little form which describes your CDRW drive and its
capabilities.

	At this point, both systems behave the same way.

	The trouble comes any time I want to use cdrecord on the
system with the Sony drive.

	Cdrecord starts out normally and then fails with an error
saying that it can't find /dev/pg0.  /dev/pg0 is the first
parallel port SCSI device.  I could certainly build a new kernel
with parallel SCSI support, but is this really necessary?  The
CDRW drive connects to an IDE controller, not the Printer port.

	I am confused.  That system does appear to be otherwise
quite functional.

Hi,
when starting cdrecord, do you specify dev=x,x,x giving the scsi 
parameters
for the sony or do you use a device?
If cdrecord is using some default it can maybe do something like what you
are getting.
Just an idea,
regards, Willem

What exactly is your kernel version, cdrecord version, the command line 
you used to start cdrecord (please use -v option) and messages displayed?



> parallel port SCSI device.  I could certainly build a new kernel
Hmm, do you have an entry in /dev for pg0, pg1, and so on?

On my system there are entries for pg0 .. pg3 which are defined as 
character devices with major number 97 and minor numbers 0 .. 3

	Here is the exact command I send taken from a script that
works on the one system that now does record

mkisofs -l -R -q /home/martin/dsp |cdrecord -v -dev=0,0,0 -dummy  -

	The dummy flag just makes it run without actually turning
on the laser for writing.  The working system goes through all
the steps while the system still having problems complains about
/dev/pg0 and gives up.

scsidev: '0,0,0'
scsibus: 0 target: 0 lun: 0
cdrecord: No such file or directory. Cannot open '/dev/pg0'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root.

I forgot to mention all the important details.

	First, the output of the tests:
