Hi

I am trying to burn data to a DVD. I checked scsi number of by DVD drive and found out it as 4,0,0.

I used the command

cdrecord dev=4,0,0 padssize=63s -pad -dao -v -eject /home/kd/Desktop/Thumb

I am getting error:

linux-vfjg:/mnt # cdrecord dev=4,0,0 padsize=63s -pad -dao -v -eject /home/kd/Desktop/Thumb/

what does it mean? How to rectify this. Please help

first you need to
then if this is going to be the only recording session on this disk
if there are going to be later additions you need

man cdrecord
man mkisofs

You are also better off using ATA:4,0,0 as the device.

If you are going to burn complete disks regularly, you can alias the command line :
Put the above in ~/.bashrc
log out and then back in
then you can use
from a command line.

Thanks for helping me!

I successfully created ISO file of my data. Then I got write error :

You suggested me to use ATA:4,0,0 as device. How can I use that? Sorry for being dump

Again I tried to burn using another DVD. I used command :

cdrecord dev=4,0,0 -multi -tao -v -eject Thumb.iso


what happened is really astonishing! When I opened burned DVD, the data on it was RHEL/5.3DVD. It is true that once I have stored RHEL image on my hard drive. I have formated entire hard drive after that and current RHEL.iso file is not available.

The data that I compiled for Thumb.iso is contents from my USB Flash drive. It was some multimedia and ebooks. I am wondering how it turned out to be an RedHat DVD!!!

Below is output with error :

the dev=ATA:4,0,0 replaces the existing dev=4,0,0

Your second attempt was writing to a full disk.

Drop the burning speed down to 8x or 4x

You can look at my previous post to see how.

Make sure the iso is not too big for the disk.

add this to your command too

driveropts=burnfree
