Hello,

I'm trying to write the rhel-5.2-server-x86_64-dvd.iso image to a dvd from a RHEL 5 system. I tried:

cdrecord -v speed-8 -dao -dev=3,0,0 -driveropts=noburnfree rhel-5.2-server-x86_64-dvd.iso

but could not mount or boot from the resultant disk. So I then tried growisofs:

growisofs -dvd-compat -speed=8 -Z /dev/dvd=./rhel-5.2-server-x86_64-dvd.iso

and it refuses because more than 50% of the space will be wasted. I don't care, I just want it to write.

Does anyone know the correct syntax for cdrecord or another command that can be used to write the image to a DVD?

Thanks,

Brad

You mean to say you could burn successfully but that DVD later was not booting RHEL?

I'm not familiar with all the options of cdrecord but is -driveropts required?

Also, as per yolinux tutorial on cd burning, dev=3,0,0 is for 2.4 kernel and dev=ATA:3,0,0 for 2.6 kernel. On the other hand I had an issue where both dev=x,x,x and dev=ATA:x,x,x did not work. I had to use dev=/dev/sr0 in the above command.

Btw, is -dev= correct usage? Isn't it just dev= ?

If you have already burnt the dvd you can check under the images folder on the dvd and burn an image to cd, which will boot your pc then enables the rest of the process to continue from your unbootable dvd, I had the same problem trying to boot a fedora dvd.

The extra "-" was just my transposition error. Driveropts isn't required. I just wanted to make sure that burnfree was turned off. The dev syntax is correct. I have made cds on this drive with that syntax and that is what is reported by "cdrecord -scanbus." Cdrecord seemed to write successfully. I just can't mount the resultant disk and thus I have no way of checking anything on the disk.

A thought, does anyone know the correct syntax to use dd to write an ISO image to a disk, or maybe the correct mkisofs syntax?
