Burn Mulitple cd's at once?

Burn Mulitple cd's at once?

[Todd Patton]

Does anyone know if this is possible in Linux. I can do it in M$ Win 
with Nero but the NEroLinux left this feature off. Basically I want to 
burn 4 copies of a folder or image at the same time. Thank you for any 
responses.

Could I ask you to explain what you want to do it a bit more detail?

Do you mean you have 4 CD burners in your workstation and want to burn 
the same image to all four of them simultaneously? If so, the only 
obstacle to doing that is the speeds of everything ... if the hardware 
can keep up, you can do it with cdrecord (and probably other apps too).

If you mean something else ... could you describe it more exactly?

I don't use Nero (on Windows) or NeroLinux ... on Linux, I burn my CDs 
with cdrecord and mkisofs, and  on Windows, I use whatever app comes 
free with the drive (which, by the luck of the draw, has never been the 
"lite" version of Nero) ... so perhaps your question will mean more to 
someone who does. If you, you might just want to ignore this and wait 
for someone else to respond.

I was unaware that it could be done using cd burn. I always have to 
choose a recoder when using the gui front end and never see an option to 
choose all recorders like in Nero.

I often have to make 20-30 copies of cd's for proposals, and was looking 
to do four at a time. Speed wise, I might bring it down to 2 burners on 
two machines as not to bog down the ide channels. But basically I just 
want to create a basic bare bones disk duplicator. Thanks for the response!

Hi, Todd:

Assuming that your 4 cd burners are configured as SCSI or SCSI emulation
and are channel 0, id 0, lun 0,1,2,3:

#!/bin/bash
#
# /usr/local/bin/burncd.sh
#

eject
cat /usr/local/bin/burncd.sh

echo ""
echo " First argument is <$1>."
echo "Second argument is <$2>."
echo ""

if [ -n $1 ] ; then
 if [ -n $2 ] ; then
  cdrecord -v dev=0,0,0 fs=64M speed=$2 driveropts=burnproof gracetime=2 
$1 &
  cdrecord -v dev=0,0,1 fs=64M speed=$2 driveropts=burnproof gracetime=2 
$1 &
  cdrecord -v dev=0,0,2 fs=64M speed=$2 driveropts=burnproof gracetime=2 
$1 & 
  cdrecord -v dev=0,0,3 fs=64M speed=$2 driveropts=burnproof gracetime=2 $1
 else
  echo "Second argument is burn speed [1 - 52] and must not be null."
 fi
else
 echo ""
 echo "First argument is filename.ext and must not be null."
 echo ""
fi
eject
mount /mnt/cdrom
ls -l /mnt/cdrom
umount /mnt/cdrom
echo $1
badblocks -vc 256 /dev/cdrom
eject

Overwrote bootloader

[sumit kalra]

Hi All,

I have a dual boot machine (Win XP and Fedora Core4)
using grub as the bootloader. The loader was working
fine for both Windows and Linux till I started playing
around with it.

I edited /etc/grub.conf and ran 'grub-install
/dev/hda8' (windows partition) instead of 
'grub-install /dev/hda' so basically the Linux
bootloader has overwritten the Windows boot loader.
Realizing my mistake, I ran 'grub-install /dev/hda'.

If from the main grub screen I choose 'Linux', I can
boot into Linux but if I choose 'Windows' I get to the
same bootloader again.

Another problem, I can't mount the windows partition
(NTFS) since FC4 apparently doesn't support it.

Can I, in anyway, recover the Windows bootloader?

Thanks,
Sumit

If you boot off the windows cd you might be able to use the "automatic
recovery mode". MS might have more info on reinstalling their
bootloader on their website.

The Linux-NTFS project (http://linux-ntfs.org/) has kernel modules
that can be installed so you can mount NTFS read-only. Currently there
are two write modes available. There is the half-working-but-safe
mode. This lets you do a few simple file operations. The other mode is
"experimental". You can perform all operations but there is a chance
that it will hose your entire file system.

Re: Burn Mulitple cd's at once?

[chuck gelm]

Chuck I keep getting an error on the last line syntax error: unexpected end
of file

I tried adding "exit" to the script but it didn't change the error. -Just
moved the line number down one. 

The arguments print correctly,
First argument is filename
Second argument is speed

<Those are only echo statements.  They do not indicate that anything happend.
 It does indicate that you entered

 "burncd.sh filename speed"

 Whereas you should have entered something like

 "burncd.sh badabing.iso 52"

 :-|   >


however there is no action on the cd drives.

I checked the numbers with cdrecord -scanbus and made the approriate
changes.

<Show the output of "cdrecord -scanbus".>

Any ideas? Fedora 4 

/Todd

Hi, Todd:

 You must be root or 'sudo root' :-|

 Show the exact command.
What is the output of 
 cdrecord -version
 cerecord -scanbus

 There are some linefeeds in your post that should not be in the script.
They may have been generated by my email viewer.  :-|
"cdrecord -v dev=0,0,0 fs=64M speed=$2 driveropts=burnproof gracetime=2 $1 &"
is one line.

 What are you entering as the first argument?
 What are you entering as the secord argument?

 You can leave out the speed argument from the script as I think cdrecord
will attempt to burn at the maximum speed reported from the CDRW device.

 You can leave out 'gracetime'.  This will result in the default wait time
before burn.

 If burncd.sh is in your path, your command should look something like this

burncd.sh yabadabadoo.iso 52



HTH, Chuck

Hi, Todd:

(Your query was very similar to a recent one on the linux-sig@dma.org 
mail list.
 Subject: [Linux-SIG] multiple CD burner)

Yes.  I did it last night.  Here is what I have and what I did.
Slackware v10.2, kernel 2.4.31, (cdrecord seems to be a soft link to
Cdrecord-Clone v2.01 by J. Schilling) Linux sg driver version 3.1.25.

I have a CD-RW(52x) in /dev/hdc and a DVD-RW(CD-40x) in /dev/hdd.
Both use SCSI emulation initiated in lilo.conf as
append="hdc=ide-scsi hdd=ide-scsi".

cdrecord -scanbus
0,0,0  CD-RW
0,1,0 DVD-RW

ln -s /dev/sr0 /mnt/cdrom
ln -s /dev/sr1 /mnt/dvd

/#!/bin/bash/
/#/
/# /usr/local/bin/burn2xcd.sh/
/#/

eject /dev/sr0
eject /dev/sr1

*cat* /usr/local/bin/burn2xcd.sh

****  *cdrecord* -eject dev=0,0,0 fs=64M driveropts=burnproof gracetime=2 $1 *>* /home/sr0.txt *&*
  *cdrecord* -eject dev=0,1,0 fs=64M driveropts=burnproof gracetime=2 $1 *>* /home/sr1.txt 
//

# end /usr/local/bin/burn2xcd.sh

  First burn was from a 618MB file over my 100 MB network with 'speed=24'
specified on both commands.  It took nearly 20 minutes with a reported 
speed of 3.6x.  :-|

 Next, I removed the speed specification and copied the ISO file to a 
local drive.
'burn2xcd.sh'  then displayed burning the CD at 48x and the (CD in the) 
DVD at 40x .
Although the CD burn was started in the first line and the DVD drive in 
the second and
the CD speed was 48x and the DVD 40x, the DVD finished first.  :-| 
I did not find the exact time elapsed, but it seemed to be in the 5-10 
minute range.

 To decrease the elapsed time of the media burn, one might put each 
media writer
on a separate controller (I have some Maxtor/Promise ATA-100 and ATA-133
IDE controllers) and put copies of the ISO images on separate drives on 
separate
controllers.  Best might be putting the ISO image(s) in a RAMDISK!  ;-)

 If you simply want to make as many copies as you have controllers at 
one time
and come back hours later, just leave of the "&" and let the commands run
one at a time.

 If you are to copy as fast as possible and stay with the computer to 
exchange media,
then perhaps multiple consoles, one for each drive, with the ISO image 
in RAMDISK,
and the writers on separate controllers.

HTH, Chuck

Todd:

 (1)
What does
cdrecord -scanbus
 display?

I am confused by your use of:

dev=ATAPI:0,1,0

Where does it say that cdrecord uses an ATAPI device?
I thought cdrecord expects to write to a SCSI device!!!

(2)
You do not need to preceed the script (burncd.sh) with 'sh '

if the script (burncd.sh) is 'executable' (and in your $PATH).

 Else, if not executable, remove the #!/bin/bash and preceed the command 
with 'sh '.

What is the 'path-to' and filename of the ISO?
 /home/username/filename.iso ?????
 Is your ISO file name really 'filename.iso' ?!?!?!?!?!?!?!

(3)
Is your default shell 'bash' ?
Are you 'root' ?

(4)
Show the exact command line.
Show the exact error message.
Show the exact path and filename of the ISO file.
