8 Copying System Diskettes

Now that you have set up your system and loaded MS-DOS, it is important that you make copies of your system diskettes right away. Use only the copies (usually called working copies) for daily

operation; store the originals in a safe place.

To copy your system diskettes, you need three blank, 720KB, double-sided, double-density, 3 1/2-inch diskettes. Follow these steps:

1.Write-protect your original system diskettes. This protects the diskettes from accidentally being erased or copied over. The write-protect device is a small switch on the lower-right corner on the back of the diskette. To write-protecta diskette, slide the switch down toward the edge of the diskette so there

is a hole where the switch used to be. (For more detailed instructions, see “Write-Protecting Diskettes,” in Chapter 4.)

2.Insert the Startup/Operating 1 diskette in the diskette drive if it is not there already.

3.Type DISKCOPY and press Enter. The screen displays this message:
