A and a second diskette drive as drive B If you have only one diskette drive MS DOS can treat it as both A and B when you need to perform operations that normally would use two diskette drives For example if you enter a command to copy data from A to B MS DOS copies the data from the first diskette you place in the drive which would be drive A to the computer s memory Then MS DOS prompts you to insert another diskette for drive B and copies the data from memory to the new diskette When copying is complete you see a prompt to insert the original diskette A Because you may often swap diskettes this way it is important to remember which diskette is which It is also a good idea to write protect your original diskette See Write protecting Diskettes above If you have a hard disk and one diskette drive you can load the operating system and application programs from the hard disk create and store your data there and use the diskette drive just for copying data to or from diskettes However if you have only one diskette drive and no hard disk you need to use that drive to load the operating system as well as any application program you are using First insert the operating system diskette the MS DOS Startup diskette for example in drive A and load the operating system this copies it to the computer s memory RAM so you do not need to leave the system diskette in the drive Then remove the system diskette and
