Copying CD without GUI

c0c0deuz · 12-02-2002, 03:42 PM

I know that it is possible to copy a disquette as an image. Is it possible to copy a CD with a command like cp in one shot?

Not really. You could do it in two, though!
dd if=/dev/cdrom of=/home/username/cdimage.iso
cdrecord dev=0,0,0 /home/username/cdimage.iso
The above should work if you:
a) have your cdrom device on /dev/cdrom
b) have your cd burner as device 0,0,0 (use cdrecord -scanbus to check).

Will it detect the max record speed automaticly?

I have a cd-rom and a cd-burner can i say:

cdrecord dev=0,0,0 /dev/cdrom?

No. The man page, however, states:

Code:

       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  and  about 172 KB/s for CD-Audio.  If no
              speed option is present, cdrecord will  try  to  get  the  speed
              value  from  the CDR_SPEED environment.  If your drive has prob-
              lems with speed=2 or speed=4, you should try speed=0.

Perhaps this would work for you, then:
dd if=/dev/cdrom of=cdimage.iso
cdrecord dev=0,0,0 speed=XX cdimage.iso

lunching the first command, i had a message:
spurious 8259A interrupt: IRQ7
but it seem likes it's continuing... should i continue on with that image?

Wow! I love Linux...
I understand that the ¦ sign can put two command together and execute them one after the other...
So would the fallowing is correct (synthax wise)?

dd if=/dev/cdrom of=cdimage.iso¦cdrecord -v dev=0,0,0 speed=8 cdimage.iso

Well, not really. the pipe | will place the output of the last command into the next command, AFAIK. You might be able to do it with:

dd if=/dev/cdrom of=cdimage.iso &&
cdrecord -v dev=0,0,0 speed=8 cdimage.iso

&& means, if this command finishes without errors, then go ahead and perform the next one. I think that'd be more what you want.

Cool

What is potentially even cooler, is if you had the parameters for burnproof in cdrecord, you could possible do this:
cdrecord -v dev=0,0,0 speed=X `dd if=/dev/cdrom of=cdimage.iso`
Or would that not work?

people seem to be missing the actual point of moduliarizeditionism software:

dd if=/dev/cdrom | cdrecord dev=0,0,0 speed=5000 -

no need for a temporary file or anything.

acid_kewpie · 12-03-2002, 09:00 AM

grant, that wouldn't work as `dd blah` would actually just equate to the output of dd:

Code:

3480+0 records in
3480+0 records out

not hugely useful huh?

Thymox · 12-03-2002, 09:05 AM

D'oh! Guess I use too little bash.

Chris, say what? moduliarizeditionism???

I get your point, so no need to clarify it, but where'd you get this word from? Is this another American English vs UK English problem or what?

Hey, that's cool about the command though, I wouldn't have thought of that, thanks.

Cool

want to add another

cat /dev/hd? >> isoname.iso

acid_kewpie · 12-04-2002, 02:40 AM

well seeing as that doesn't answer the question... not really
