How to create an ISO image file from a disc under UNIX.

[valeyard1492]

This is much simpler than it is under windoze. The disc must not be mounted and not encrypted.

In fact, all it is a simple command line:

bash-2.05# dd if=/dev/dsk/c0t1d0s2 of=/data/ISO/powerdvd4.iso

where:

if in file is the device file for the cd/dvd-rom drive
of out file is the path where you want the image created.

I used this method recently to back up CDs on to a DVD, because it is not only simpler but also free.

Some systems don't automagically know how big the CD is, so you have to supply the bs= and count= options to dd. On OpenBSD you have to run disklabel on the CD to get the bytes/sector and total sectors, so it would be:

# disklabel /dev/foo
# dd if=/dev/foo of=file.iso bs=bytes/sector count=total sectors

... which can easily be automated with a shell script.

you think this is simpler than windows where all you have to do is click ONE button ??

[mats.hogberg]

Could you please tell me how to create an ISO file from a CD with just one mouse click under Windows?

if a dvd:

put disk in tray and hit MODE Read with DVD Decrypter

if a cd , load cd and use recordnow max or cdrwin and create image .. doesnt also nero have this feature ? there are other apps that can do this also pretty darn easy ..

[mats.hogberg]

And how do you start DVDDecrypter and/or RecordNow Max and/or CDRWin and set the correct options in those by just clicking one button?

no options to set ...

i said one MOUSE button ..

you have two keyboard buttons to use to open the program if it is not already running (or you could use your mouse also - then it wouild be three clicks) ...

vs. having to type out a command line and opening a command window and figuring out:
"bs= and count= options to dd. On OpenBSD you have to run disklabel on the CD to get the bytes/sector and total sectors, "


clone and some others i think it is either 3clicks or one click and 2 keyboard ..


i just tried nero and it is 3 mouse clicks from opening the program to finish to create a iso ..

clearly unix is not "simpler" than windows (and i am an unix user (sgi) - nothing generally is easier)

However, under Windows you need to download and install Nero and/OR CDRwin and/OR DVD Decrypter.

dd is included in any *nix.

Seperating intuitivity (how obvious something is) from ease of use (how quickly it can be done when you know how), I would say linux has better ease of use, but Windows clearly wins in the intuitivity category..

You can always use K3b under linux to create an ISO of any file and it's just one click. It's included in most Linux distros and no setup required.

I'd just like to set a know it all straight - dont talk crap to people trying to help one another huh? Not that this post makes less of spamming in the thread but..

What part of 'under UNIX' dont you get from the subject of this thread?
And - do you realize what you are saying?
step 1)
search for application
step 2)
download and save zip
step 3)
unzip (with having to select location - click click)
step 4)
install - click click, re-taint the allready way-too-full registration database
step 5)
open GUI blurt
step 6)
do your thaing!

dd is a basic unix tool that have been around for ages - and even my 16MB router (with UNIX) knows this trick. Hell, it runs on floppy omg.. Instead of cdrUms i sometimes pipe my ethernet packages through dd into a log - id like to see u do that in a 'click'

Of course you can just alias the command to the letter 'i"

Then it's just 2 keys, i and <enter>
or
in script, 1 double-click on desktop (guess it counts as 2 clicks)

tuxprobe and junktodevnull - So, neither of you could leave this old thread alone? Damn, 5 years of silence and now you both have to needlessly add to it. If the thread is more than a few months old, don't add to it unless what you have to say is absolutely critical. Neither of your posts fall under that category.

To be fair, junktodevnull was just responding to a thread that tuxprobe reactivated. So tuxprobe - are you unable to read that the last post was over 5 years ago? Thanks for nothing. And for the record, I work as a Unix System Administrator and I am no fan of Windows, but it was really unnecessary to dig up this old thread to post to it.
