Description of problem:
Unable to burn cd's with external USB-2.0 Pacific Digital X-Treme-16
cd-rewriter.  This cd-burner worked fine with the 2.4 kernels on prior
Redhat installs.  I'm able to mount the drive, while it has data  cd's
in it, but am unable to burn with it.  I've attemped to burn a cd with
cdrecord, and using the Nautilus CD-Creator.  The hardware browser
recogizes this cd-burner as:

Device = Lite-on LTR-16102B
Manufacturer = Lite-on
Driver = none or built-in
Device = /dev/scd0

When I connect the drive I get the following message in my system log:

My internal cd drive (Non-writable) in the hardware browser is (if
this helps):

Device: Samsung CD-ROm CD-140
Manufacturer: Samsung
Driver: None
Device: /dev/hdc

This drive hasn't been recognized under Redhat, since around RH-7.x. 
When I run cdrecord -scanbus, the first time I get some system log
errors which deal with my internal cd drive.  Please refer to the

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Connect drive, and turn on.
2. Use cdrecord, or Nautilus CD-Creator to attempt to burn a disc.

Actual Results:  When using the Nautilus CD-Creator, I get the folling
error message:

cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you
are root.
cdrecord: No such file or directory. Cannot open '/dev/sg*'. Cannot
open SCSI driver.
scsibus: 1 target: 0 lun: 0
scsidev: '1,0,0'
cdrecord: WARNING: This causes a high risk for buffer underruns.
cdrecord: Permission denied. WARNING: Cannot set priority using
cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler
cdrecord: WARNING: This causes a high risk for buffer underruns.
cdrecord: Operation not permitted. WARNING: Cannot do mlockall(2).
cdrecord: Continuing in 5 seconds...
cdrecord: Future versions of cdrecord may have different drive
dependent defaults.
cdrecord: Asuming -tao mode.
cdrecord: No write mode specified.

It looks like that Nautilus is attempting to burn a disc with my
internal cd-drive (based on the SCSI id), even though it's not a

Expected Results:  Burns the cd.

# cdrecord dev=/dev/scd0

Comment 3 Brian Pepple 2004-05-24 11:45:20 UTC
I'm able to burn a disc using:

cdrecord dev=/dev/cdrom1

I'm still unable to play audio cd's with either drive, though.
