DOS commands like this are usually self documenting i.e.
display a list of available and necessary parameters if you
key FILENAME /?
or in this case FORMAT /?

WinXP handles this sort of task more conveniently via
/ Control Panel / Administrative Tools / Computer Management
/ Storage / Disk Management.
You can here remove all volume(s) from the HD, make a new
one (or several) and format it.

If you are booting the computer from the hard drive that you are trying to
erase that can't be done. What you are effectively trying to do is cut off
the limb that you are sitting on and in this case Windows will not allow
that.

You either need to get your CD drive working so you can boot from that, boot
from a USB thumb drive that has the DOS operating system on it and the
format program or use a floppy drive with the system files on it to boot the
computer.

The format command would be Format C: <ENTER> from whatever boot media you
use (other than the Windows Operating system command line of course.)

I don't have the install disc, or a floppy drive on this laptop. I
guess there is no way to erase it then?
