Other Help Topics :: create iso image from a cd or dvd

unable to create iso from a cd or dvd

using dsl-4.2.3, booting from floppy to usb (dsl fromusb) in order to use the cd/dvd writer

tried multiple variants of the following command with no success

dd if=/dev/cdrom of=file.iso bs=1024

once able to extract the iso, what is the command to write the iso to a cd or dvd?

thanks

first check your burner's device number with "cdrecord -scanbus"
Then burn your iso with "cdrecord speed=8 dev=1,2,3 -data file.iso", substitute your device number for 1,2,3

What errors do you get when using that dd command?

dd if=/dev/cdrom of=file.iso bs=1024

dd: reading '/dev/cdrom': Input/output error
497366+0 records in
497366+0 records out

creates a 0 byte file.iso

bash: cdrecord-scanbus: command not found

dd if=/dev/cdrom of=file.iso bs=1024

dd: reading '/dev/cdrom': Input/output error
497366+0 records in
497366+0 records out

creates a 0 byte file.iso

Maybe there's not enough room in the directory where you're trying to write file.iso
Or maybe it's not writeable by you as user dsl? root?

I just went to a root shell, was in /home/dsl, and did:

Code Sample

dd if=/dev/cdrom of=file.iso count=10 bs=1024

and indeed a file.iso was created:

-rw-r--r-- 1 root staff 10240 Jan 21 16:46 file.iso

Quote

bash: cdrecord-scanbus: command not found

The command is cdrecord , and the option is -scanbus; so leave a space:

Code Sample

cdrecord -scanbus

thanks for your reply, still no success with dd, your clarification on the -argument for cdrecord resolved that situation

here are the commands i typed to create the iso

sudo su
dd if=/dev/cdrom of=file.iso count=10 bs=1024

system response
dd: reading '/dev/cdrom': Input/output error
0+0 records in
0+0 records out
0 bytes transferred in 0.007514 seconds (0 bytes/sec)

appreciate your help, have 4gb of free space (/home/dsl/) for the cd iso
