Formatting a cd?

Two questions:

1.)I'd like to backup the output of my batch file to a cd. Is it necessary to format the cd to fat32?

2.)When I type the command, >format d: /fs:fat32

I get the warning: ALL DATA ON NON-REMOVABLE DISK DRIVE D: WILL BE LOST.

The cd is of course, removable. I'm not going to hurt my C: drive, am I?

You don't need to format the cd. 

Unless it's a rewritable disk formatting it is like writing to it.  It will make it into a coaster.

It's a read-write disk.

So, the format command is only used now for the hard drive since floppys are obsolete?

Correct.  Don't format your cd's.  The utility that you use for creating the disk will take care of what you need.

you need to format them if you use packet writing software; which would appear to be the case here.

You know, I had forgotten about that.  Good catch.
