FC9 : DVD ROM detection and writing

Hi,

I have Fedora release 9 (Sulphur) in TEXT ONLY mode.

I have a Samsung DVD writer connected to it.

I want to backup my data to a DVD.

I have 2 hurdles:
(a) How do I detect my DVD rom drive and mount it.
(b) How do I write data to the DVD.

I am relatively new.

Please suggest pointers or steps.

Thx
Vai

One straightforward way is to look through /var/log/message where the loading kernel detects its hardware

Newer systems usually have some hotplug functionality. You can just insert a dvd, close the drive, and wait for a popup to ask what you want to do with it. Say open and the file manager will show its contents. Now "mount" will show you the name of the device and where it is mounted.

Is this the DVD ROM ??

What next ??

Here's how I would do it.
First run 'lsscsi':

Code:

bash-3.1# lsscsi

[3:0:0:0]    disk    ATA      ST3160815AS      4.AA  /dev/sda

[5:0:0:0]    cd/dvd  TSSTcorp CDDVDW SH-S203D  SB00  /dev/sr0

So in this case the drive is /dev/sr0. Usually there's a symlink from /dev/cdrom, so you can use that too, but not if you have more than one DVD drive.

You can also find out more info on the drive using:

Code:

cdrecord -prcap dev=/dev/sr0

Now, to burn your data you do NOT need to mount the disk, in fact you can't, it's impossible.

To write the data, read about it here:
http://www.linux.com/feature/113859

Or you can use my script:
http://draconishinobi.50webs.com/sla...ul-scripts.tgz
It's called 'burnit' just run 'burnit directory /dev/sr0'.
Or just run:

Code:

growisofs -dvd-compat -speed=1 -use-the-force-luke=bufsize:32m -Z /dev/sr0 -graft-points -rational-rock -full-iso9660-filenames -iso-level 2 source_directory

Where source_directory is the directory you want to burn, and with the appropriate speed setting (here it's 1x)

Thx for your details ionstructions.
I am sure it will be of great help.

When I hit lsscsi I got this error.

[root@server ~]# lsscsi
-bash: lsscsi: command not found

Is lsscsi not included in the std FC9 distro or have I stopped some services ??

Thx for your help.

It's probably not included, in which case, how many DVD drives do you have ? If only one, then use /dev/cdrom or /dev/dvdwriter those symlinks should be there

I have 1 ROM.

But the output id different.

The outpur of lsscsi is as follows:

Code:

[root@server ~]# lsscsi

[2:0:0:0]    disk    ATA      WDC WD1600AABS-0 01.0  -

[root@server ~]#

I will just check if the ROM is well connected and showing up in CMOS.

H_TeXMeX_H

05-04-2009 02:46 PM

It doesn't seem to be detected.

vaibhavs

05-05-2009 08:19 AM

Figured out the ROM was not powered & its a CD ROM not DVD :(

Now I see this.

Code:

[root@server ~]# lsscsi

[0:0:1:0]    cd/dvd  SAMSUNG  CD-ROM SH-152A  C501  -

[2:0:0:0]    disk    ATA      WDC WD1600AABS-0 01.0  -

and I see this:

Code:

[root@server ~]# ll /dev/cdrom

lrwxrwxrwx 1 root root 3 2009-05-05 17:06 /dev/cdrom -> sr0

So now I have recognised the ROM.
Now the burning part....

vaibhavs

05-05-2009 08:24 AM

I will try this command to test a burn

Code:

growisofs -dvd-compat -speed=1 -use-the-force-luke=bufsize:32m -Z /dev/sr0 -graft-points -rational-rock -full-iso9660-filenames -iso-level 2 source_directory

But 1 question, how do I define multiple files & folders in the command ?
Is it like

Code:

source_directory1, source_directory2, source_directory3, source_file

Or is there any other way ?

Thx
Vai

FC9 does not have growisofs

Code:

[root@server ~]# growisofs -dvd-compat -speed=1 -use-the-force-luke=bufsize:32m -Z /dev/sr0 -graft-points -rational-rock -full-iso9660-filenames -iso-level 2 /var/www/html

-bash: growisofs: command not found

[root@server ~]# which growisofs

/usr/bin/which: no growisofs in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)

[root@server ~]#

vaibhavs

FC9 does not have "mkisofs" either which is required for "growisofs".

Please help, what utility should I use/install for CD/DVD burning in FC9

Thx
Vai

H_TeXMeX_H

You can also use cdrecord to burn a DVD, I've never done it tho, I prefer growisofs. But you'd probably run this:

Code:

mkisofs -graft-points -rational-rock -full-iso9660-filenames -iso-level 2 source_directory | cdrecord -v gracetime=2 dev=/dev/sr0 speed=1 driveropts=burnfree -tao -

To burn more than one directory just list the rest of them after that first one.

But, as you will notice from the above, you cannot backup data files to a data dvd or cd without mkisofs ... you can't make an iso ... therefore what are you gonna burn ? Nothing. Therefore you must first install mkisofs, and I recommend growisofs too.

I believe it's part of the dvd+rw-tools package.

vaibhavs

05-05-2009 01:09 PM

Ok.

dvd+rw-tools package does not include mkisofs
See this:

Code:

[root@server ~]# rpm -ivh dvd+rw-tools-7.0-11.fc9.i386.rpm

error: Failed dependencies:

        mkisofs >= 2.0 is needed by dvd+rw-tools-7.0-11.fc9.i386

So I had to first install genisoimage-1.1.6-11.fc9.i386.rpm & then dvd+rw-tools-7.0-11.fc9.i386.rpm

But this could not burn a CD.

Code:

[root@server ~]# growisofs -dvd-compat -speed=1 -use-the-force-luke=bufsize:32m -Z /dev/sr0 -graft-points -rational-rock -full-iso9660-filenames -iso-level 2 /var/www/html

:-( /dev/sr0: media is not recognized as recordable DVD: 0

What are my options to burn a CD ?

Thanks for your continued help.
Much appreciated.
