cdrecord makes cd unreadable

7smurfs · 06-29-2005, 07:21 PM

Ok, after finally getting my cdrw drive to work, I tried to burn a cd.

Well, I burned two cds in the following way:

Code:

cdrecord dev=0,0,0 /root/Desktop/(file here, ex: d.txt)

and it seems to happily oblige. However, after remounting the cd I get an error that it is write only(?) and can not be mounted.

Does anyone have any suggestions on what it could be?

You normally would need to make an iso image of the data, then burn the image using cdrecord.
For example:

Code:

cd /mnt/tech
Create an iso image: mkisofs -R -J -hide-rr-moved -o /home/myfiles.iso .
cdrecord -v dev=0,0,0 -data /home/myfiles.iso

or you could skip a step and do it this way...

Code:

cd /mnt/tech
mkisofs -R -J . | cdrecord -v speed=24 dev=0,0,0 -eject -data -

Will I still be able to burn multiple files though? (I.e, File1.iso now, and a week later File2.iso) I would test it myself but I don't want to waste another CD, I'm running low ><

That is called multi session which I didn't know you wanted to use.
Also, my system appears to be somewhat newer than yours and my device is called like this:
dev=ATA:1,0,0
so you can change that part to match what you have been using... dev=0,0,0

Here are my notes on multisession cd recording...

Code:

#All images must have "-multi" used on all cdrecord sessions.

For example: I have two folders which I want to record.
I am going to use -graft-points so the folders are created 
and all data is put inside them.

/mnt/tech/achome
/mnt/tech/aclinux

#The first mkisofs session is generated as normal.

cd /mnt/tech

mkisofs -R -J -graft-points "achome=./achome" |\
cdrecord -v dev=ATA:1,0,0 -multi -data -

#Additional sessions must have the track number ( -C # ) included when generated.

cd /mnt/tech
next=`cdrecord -msinfo dev=ATA:1,0,0`
echo "Next Track is $next"
mkisofs -R -J -o /home/mystuff.iso -C $next \
-M /dev/cdrom -graft-points "aclinux=./aclinux" |\
cdrecord -v dev=ATA:1,0,0 -eject -multi -data /home/mystuff.iso

#To burn additional sessions directly to the cdrom....
cd /mnt/tech
next=`cdrecord -msinfo dev=ATA:1,0,0`
echo "Next Track is $next"
mkisofs -R -J -C $next -M /dev/cdrom -graft-points "aclinux=./aclinux" |\
cdrecord -v dev=ATA:1,0,0 -eject -multi -data -

You may find the information at http://www.brandonhutchinson.com/Bur..._cdrecord.html very useful.
