C doesn't know anything about a CD drive. Your computer knows about the CD drive, because it has a driver that handles it. C just passes the request along to the operating system, and the operating system passes it along to the driver.
That's why you can't use a device, until you have a driver for it.

You should be able to access any drive - hard drive, floppy drive, or cd drive - just by changing the letter of the drive, in your program.
You want to *definitely* use high level stream file functions, not low level non-stream, functions.
Remember that a floppy or CD drive, will have much slower access times, compared to a HD, so you may need to introduce a delay() or a very short sleep(). Just a second or two, should be enough, if it's needed at all.

Lemme guess.
You've found an example for your fossil C compiler (TurboC) that accesses the floppy disk (but it knows nothing about CDs, since it pre-dates them by a few 1000 years).
On the other hand, your brand new machine is so new that floppies are ancient technology (last used by druids), and it only has a CD.

Can you explain the context of the problem ?
