ISO is a disk image / archive file of an optical disc defined by the International Organization for Standardization. ISO image files typically have a file extension of .ISO and is supported by many software vendor. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but an ISO image can also contain UDF file system because UDF is backward-compatible with ISO 9660. An ISO file contains the image of a disk, meaning that it contains every file and folder structure that the disk had.

There’s nothing about the ISO format that actually knows about files, folders or formats. It’s just the raw data from the disk. Now, naturally that raw data, if interpreted correctly, may know about files, folders and format. But, like a disk, the operating system has to look, see what format was used (things like FAT32, NTFS and the like), and interpret the contents of the ISO file as if it were reading the raw data from an actual disk.

Creating ISO file:

1. Insert CD/DVD

2. Open Terminal, type the following command to view the

 $ drutil status
 Vendor   Product           Rev
 OPTIARC  DVD RW AD-5630A   1AHN

 Type: DVD-R                Name: /dev/disk1
 Sessions: 0                  Tracks: 2

3. Unmount the disk with the following command.

 $ diskutil unmountDisk /dev/disk1

4. Now to create the ISO file (will take sometime):

 $ dd if=/dev/disk1 of=image.iso bs=2048

It takes sometime, it took about 25 minutes for me to create an image from a DVD. After that you can see something like this from terminal.

2074720+0 records in

2074720+0 records out

4249026560 bytes transferred in 1494.992734 secs (2842172 bytes/sec)

5. Test the created ISO image by mounting or opening with Finder:

 $ hdid image.iso

6. ISO image is ready for use. Enjoy. (The default location the file will be saved is the User folder)

Hi all, today I will be writing on how to format your chat messages and all chat icons which can be used in facebook chat.

First lets see how to bold or underline the chat message:

*This is a bold message*     – This will make the text bold.

_This is underlined_     – This will make the text underlined.
