Creating an .iso Image file from a CD/DVD in a Mac
Recently I came across a problem in my office, where one of my employee's PC CD drive did not work. But had to install a software in the system. I was wondering if I can convert the entire disk contents into an .img file and then mount the same using the clone drive copied via USB pen drive. Below is the process of converting any CD/DVD into an .img file using a Mac.
Insert the CD/DVD into Optical Drive and wait for it loads.
Now Open Disk Utilities (You can get from /Applications/Utilities/Disk Utility)
After Disk Utility is loaded, you can see your disk is mounted in the left side bar of the Disk Utility. Select the Disk.
Now in the Popup box, In Save As text box, Type the Name of the image file as per your wish and select the place where to save the image file in Where section.
Select the Image Format to DVD/CD Master and Keep the Encryption option as None. Recheck the options, which should be like below image. Then hit Save button and wait till it saves the image file.
The output Image file will be in .cdr format. In Mac .cdr image works perfectly. However we have to change as .iso file format which is globally accepted by all operating systems. Now we are going to convert .cdr image file to .iso file image using terminal. So Now we are going to do something little bit typing in Terminal. Don’t worry i will guide you every single step.
Launch Terminal (/Applications/Utilities/)Now my .cdr image file is located in desktop. So Lets Navigate to desktop in terminal by following command. (use proper command to navigate to your file location.)
and hit Enter/Return key. Now your Terminal is targeting your desktop location. Now type the following command to convert the .cdr file to .iso file. ([filename] should be replaced with your file name of cdr file. Check below image.) and hit Enter/Return key. It will start converting.
hdiutil makehybrid -iso -joliet -o [filename].iso [filename].cdr
Now the terminal have converted your .cdr image file to .iso image file, which can be read by operating systems like Windows and Mac. This is the simple way to create iso image file from DVD or CD without using any third party apps. Now you can burn this iso to DVD/CD. To Mount this image just double click the file in Mac and In windows you need virtual drives to mount the iso image file. If you have any doubts, kindly drop us in comments.
