On the second day of dd, we learn about floppies and dd!

Here are the basics for copying a floppy disk. Floppy disks are great for practicing on. No chance of hurting your system.

The basic command is:

# dd if=/dev/fd0 of=/storage/floppy.img

The example assumes that your floppy drive is /dev/fd0 and that you have a directory on your system named /storage that is suitable for copy an image into. Now for the specifics of what just happened.

if - Specifies the input file to be read

of - Specifies the output file to be written

Writing the image back to another floppy disk goes like this:

# dd if=/storage/floppy.img of=/mnt/floppy

Doesn't get much simpler than that.

On the third day of dd, how to copy data from a hard drive with dd.
