Insert a floppy disk
Your computer’s floppy disk drive can accommodate 3.5-inch
(89-millimeter) floppy disks of two types:
n
high-density disks, which can hold up to 1.4 megabytes (MB)
of information
n
double-sided disks, which can hold up to 800 kilobytes (K)
of information
(The next page explains kilobytes and megabytes.)
Follow these steps to insert your new disk into the disk drive.
1. Write “Practice” on a blank disk label.
2. Attach the label to your new floppy disk.
The molding of the disk’s plastic case indicates where the
label goes. Do not affix the label over the metal shutter.
3. Hold the disk with your thumb on the label and the
metal shutter pointing away from you.
4. Push the disk into the floppy disk drive, label side up
and metal shutter first.
The next section, “Initialize a Disk,” explains what to do about
the message that appears on your screen.
