Burn ISO image

Gerardoj · 05-31-2003, 10:35 AM

Hi everyone!!

I have GnomeToaster to burn, I downloaded Slackware (Slackware-9.0-install.iso) and I would like to know how can I burn Slackware if the file size is 662.8MB but when I drag to burn appear me that the file is 778MB and my CD-R is 700MB what can I do?

Thanks

I'll use my CDRW drive as an example: HP 9100, write speed=8.

1. From console or xterm, type cdrecord -scanbus

2. You should see output like the following:
scsibus0:
0,0,0 0) 'HP ' 'CD-Writer+ 9100 ' '1.0a'
0,1,0 1) *
0,2,0 2) *
...etc...

[this output means that the cd-writer is device 0,0,0]

3. Type in cdrecord -v speed=8 dev=0,0,0 slackware.iso

[substitute the write speed of your cdrw for the speed parameter and use the device numbers from the scanbus output; use the full path for slackware.iso]

Good luck.

is iso image includes the filesystem info and other
goodies that don't count in the files space, so it's normal
for an iso image to be almost 100 meg's bigger than
the space it appears you have on the cdrom.

Thanks both,
whansard: that means that I can burn the complete Slackware-9.0-install.iso in CD-R of 700M?

Tnanks.

if you burn it as an image and don't get mixed up and
burn it as one big file.

That really helped me out. Now if I can only burn normal data cds (.avi files) from the command line :)

use mkisofs with a few options to create an
iso image with the avi file in it. then you can burn the
iso.
search for mkisofs on this site and you'll find it around.

audio cd

746.9 Mb
80min
807.5 Mb

data cd
74min
650.4Mb
80min
703.1Mb

video cd
74min
738.0Mb
80min

*snicker*

whansard: at Linuxworld yesterday Novell handed out hundreds of CDs that had an iso file on em. :P

i occasionally have my girlfriend burn me a cdrom at
work where she has very high speed access. i
always get a disk with the iso image on it. i explain it
to her, but i don't think she gets it.
I guess novell's secretary didn't get it either.
