cdrecord - no disk/wrong disk

[Susan Prosser]

cdr at /dev/dsk/c0t0d0

I cannot mount the cdrom with a blank cd in it, says devide busy.
I can run cdrecord dev=0,0,0, -inq and get some info back.
But if I try to write a directory to it, or load it, I get an error.......

Hi,

though I've never used cdrecord on HP-UX I make haevy use of it on a Linux box.

I hope the basic handling is similar.

First I'd read the manpage of cdrecord (it has dozens of options) because it really depends on what kind of image you want to write (e.g. ISO, bootable, raw data etc.)

Then check if your drive is found

Usually before you burn a CDROM you have already mastered an image.
Most of the times I use an ISO image if I need to read the CD under different OS.
Therefore you'd need some software to master this image.
On Linux I use mkisofs which today I guess is shipped together with cdrecord (at least it is maintained by the same guy J??rg Schilling).
See manpage of mkisofs for details.

Given I already have an ISO image at /opt/store/myexmail.iso I'd issue

# cdrecord dev=0,3,0 fs=4m speed=8 -isosize -dummy -nofix /opt/store/myexmail.iso

Starting to write CD/DVD at speed 8 in dummy mode for single session.
Last chance to quit, starting dummy write in 0 seconds. Operation starts.

where the dev= is the device target of your drive, the same -scanbus showed, fs= is the FIFO size, speed= is obvious.
The additional switches -dummy and -nofix will prevent the disk from actually being burned and fixated.
You would omit these after you have made sure everything works properly.

You don't have to supply most of the arguments to cdrecord, but may rather put the in /etc/cdrecord.conf.

Apart from ISO images you can also burn in raw mode by simply piping from another command if you can guarantee a continous data stream to protect from buffer underruns which could render your CD-R useless

e.g.

tar cf - /home | cdrecord -v -data -
