Using a Single Floppy Disk Drive

Usually operating systems expect the computer to have at least two
physical disk drives and display prompts and messages accordingly. If
your system has a single floppy disk drive, MS-DOS treats your single
drive like two logical drives. This helps you perform operations that
normally require two floppy disk drives.
For example, if you give a command to copy from one drive to
another, MS-DOS copies from the first diskette you place in the drive to
the computer's memory. Then MS-DOS prompts you to insert another
diskette and copies from memory to the diskette you place in the drive.
When copying is complete, you see a prompt to insert the original disk-
ette.
