Does this readcd command make an iso copy

Hello friends,

I want to copy a CD. But i was thinking of making an iso image file of the CD, to burn it later.
Does this command make a iso copy of the cd:

Code:

readcd -v dev=/dev/hdc f=cdimage.iso

Will this cdimage.iso, when burnt on the CD make an exact copy of the original CD.

I went thru the manual of readcd and found that there is a -clone option. I feel this is applicable for audio CD only. Am I wrong.

Guide me, friends.

Thanks a lot

To make a .iso file, use the dd command:

Code:

dd if=/dev/hdc of=SomeIsoFile.iso

Thanks for taking time to reply.

But it did not work out.

I should elaborate it further. I had one "System Rescue CD", of which i made a image by the "readcd -v dev=/dev/hdc f=cdimage.iso" it worked out ok. Then I burnt the image to a CD and I got my system rescue CD back. No problem here.

Now I am trying to make an image of a video CD (say a movie CD). When I give this readcd command, it makes a image of 384 KB (in 10 seconds). I tried with the dd command too as suggested by you. But of no avail.

Subsequently I used k3b package to make an image. Even this image that I got, and which burnt later to a CD, did not play.

My question is - how can I make an iso-iamge copy of a video CD ?
Incidently can anyone tell me whether the image that the "NERO" CD buring software (Windows) makes as an intermediate step while copying a CD is an iso image or some other kind of image.

Thanks once again.

In that case it's probably copyrighted content and a cd that's protected from copying.

No my friend !

It is video CD of my marriage.
ANd in linux only, I can copy the CD directly (I have two CD drives).

The "Nero" (windows )is creating a cd image. Then, I checked out out by mounting this windows partition in linnux and by "file" command, and found that the system is not able to recognise that it is some kind of image. It seems that this image is proprietory.

The problem still remains - How can I make an iso-image copy of my video CD, for burning at a later date.

Thanks for everything.

DD will most definitely make an .iso image from a CD.

Those images that Nero make are proprietary. There is open source software that'll read them. I think they're .nrg

I think nrg2iso is what you want.

This is not working. I have tried this on different CDs, and the messgae that it gives out is same every time. The message is

Quote:

[drags@localhost ~]$ dd if=/dev/hda of=img.iso
dd: reading `/dev/hda': Input/output error

I have tried with the CD as mounted and as unmounted.

On the contrary, when I tried "readcd" on the an FC5 CD, I got the iso image.

Code:

 [drags@localhost ~]$ readcd -v dev=/dev/hda f=image

Why is the dd not working inmy case, since I believe you are very sure of its desired result.

Thanks once again.
