Make sure you have enough diskettes to back up the data on
your hard disk drive. It takes about 17 1.2MB diskettes to back
up a 20MB hard disk that is completely full, and about 34
1.2MB diskettes to back up a full 40MB hard disk.
See your MS-DOS Reference Manual for complete instructions
on using BACKUP.
