HOWTO Convert various CDROM/DVDROM image types to .iso <A command line tutorial>

[oshunluvr]

After a recent bout of downloading, I found myself with several different types of CD/DVD images created on windblows machines. I prefer .iso files because it's much easer to mount, edit, extract and burn them IMO.

Here's how you convert these other types to .iso:

Types I have encountered, installing their required utilities, and the CLI entries to make them work:

MDF/MDS
sudo apt-get install mdf2iso
mdf2iso filename.mdf filename.iso

CUE/BIN
sudo apt-get install bchunk
bchunk filename.bin filename.cue filename.iso

NRG
sudo apt-get install nrg2iso
nrg2iso filename.nrg filename.iso

IMG
sudo apt-get install ccd2iso
ccd2iso filename.img filename.iso

DAA
wget http://poweriso.com/poweriso-1.3.tar.gz
tar -zxvf poweriso.tar.gz
./poweriso convert filename.daa -o filename.iso -ot iso

BONUS:
Install isomaster to view, extract, or add files to an iso.
To mount an iso and access it like a cd: sudo mount -o loop disk1.iso /mnt/disk

The Nrg (Nero image) format

About the particular Nrg (Nero image) format:

What nrg2iso 0.4 does is basically this:

dd if=/path/to/image.nrg of=/path/to/image.iso bs=1024 skip=300

That is to say, nrg2iso 0.4 basically strips the first 300 kilobytes. If we see its source code, we can see:

      [...]
      nrgFile=fopen(argv[1],"rb");
      fseek (nrgFile, 307200, SEEK_SET);
      
      isoFile=fopen(argv[2],"wb+");
      
      while((i=  fread( buffer, 1, sizeof(buffer), nrgFile ))>0){
        fwrite(buffer,i,1,isoFile);
        [...]

and so, some problems can happen.

However, iat, "Iso9660 Analyzer Tool", takes more things into account.

In very strange cases, if you have problems with iat to convert strange files from .nrg to .iso: you can use Nero Linux.
