I have a Storix USB DVD/CDRW plugged into a USB port on a PCMCIA USB card with the DSL 4.2.1 frugal install.

I have been able to read from this drive with mnt /dev/scd0 /mnt/cdrom1

though it might have been nice if it auto mounted...

But my goal is to burn an iso image to CD, so I try:

cdrecord -v dev=/dev/scd0 dsl4-2-1.iso and I get an error something like:

Read-only file system. Cannot open 'dev'scd0'. Cannot open SCSI driver.

I had rebooted the system after reading an existing CD and mount does not show the CDRW mounted right now.

You can edit your fstab if you want it to do that. As far as your other troubles, did you check permissions, mount it rw instead of ro, etc.?

I thought cdrecord wants a scsi device number (something like 0,0,7) and not a device?

Try cdrecord -scanbus to see which number your drive got..

cdrecord -v dev=/dev/scd0 dsl4-2-1.iso

This is what I use:

cdrecord -v dev=0,0,0 speed=4 data dsl-4.2.1.iso

where the numbers 0,0,0 are obtained from the command

cdrecord -scanbus

YES!!!!!

dev=0,0,1

Worked with a speed=4

Just downloaded another iso and trying it with speed=8 (what is reported as the speed of this CDRW drive).

THANKS!!!

Now to document it.

Best to write iso at slow speed.

Currently using:
cdrecord -v -eject speed=4 dev=0,1,0 dsl... to burn iso cd.
Is there a wildcard so that I may burn all my files in hda3 for year end storage?
Tried CD Burn App GUI but looks like I would have to select files one at a time

This is what I use to burn a copy of my "data" directory.
Let say on hda3 I have a data/ directory.

First mount the drive. Then:

# cd /mnt/hda3
# mkisofs -r -o /mnt/hda3/data.iso data/

This will make a iso9660 image of the data/ directory

Next use your cdrecord command to burn it.

Now you can mount this cd and there are all of your files and directories that were in the original data/ directory.
