Objectives

Explain floppy disk Explain 3.5” and USB floppy disk drives Install the floppy disk drive Configure the floppy disk drive Format a floppy disk Create a bootable floppy disk Troubleshoot the floppy disk drive



Floppy Disk

Alan Shugart created floppy disk drive

External storage device

Stores data on magnetic surface

Used for transferring data from one computer to another



3.5 inch Floppy Disk

3.5 inch had a high density and could hold 720 KB of data and then density increased to hold 1.44 MB of data.

Has two holes at the bottom of the disk. One enables to identify if floppy disk has a low density or high density and other is a write protect tab



Write Protect Tab Protects data from being accidentally modified or erased Sliding the switch down makes the floppy disk read only Sliding the switch up enables data to be read and written

to the floppy disk



Types of FDD

3.5 Inch FDD - Floppy drive spins the floppy disk at a speed of 300 rotations per minute

USB FDD - The USB FDD is a slim type floppy disk drive (FDD) with a Universal Serial Bus (USB) interface



Calculation of 1.44 MB

The total unformatted size of the floppy disk can be calculated as:

= 2 (number of tracks * number of sectors * size of each sector in a track)

= 2 (80 * 18 * 512)= 1,474,560 bytes i.e. 1.44 MB



Practical

Perform the activity mentioned in Lab no. 1 in the text book:

• To install a floppy disk drive.



Configuring the Floppy Disk Drive

Assign a drive letter A: and B: to the floppy disk drive using the data cable

Configure system BIOS to detect the installed floppy disk drive



Practical Activity

Ask the students to perform the steps to configure the floppy disk drive.



Formatting a Floppy Disk

You must format a floppy before using it.Formatting a floppy creates tracks and

sectors on the floppy disk.Formatting wipes out all the data stored on

it so copy the data to a different location before formatting.



Practical


• To format a floppy disk through the command prompt and using windows explorer.



Creating a Bootable Floppy

Contains system files for starting the system

System files • ntldr• ntdetect.com • boot.ini



Practical


• To create a bootable floppy disk for Windows Vista.



Troubleshooting the Floppy Disk Drive

Floppy disk drive may have some problems which can corrupt the floppy disk

Problems that may occur if the floppy disk drive is damaged are:

• Can not detect the Floppy Disk Drive

• Unable to read and write data to the Floppy Disk

• Cleaning floppy drive using FDD cleaning kit



Summary - I Floppy Disk is an external magnetic storage device Write protecting the floppy disk protects the data

from accidental erasure Different types of floppy disk drives are

• USB• 3.5 inch

The floppy disk is inserted in the floppy disk drive through the front plastic window called the faceplate

The floppy disk drive must be installed for the system to access it



Summary - III

Configuring the floppy disk drive assigns it the required drive letter

Formatting a floppy disk creates sectors and tracks on the floppy disk

The system requires important system file to start the system

The bootable floppy disk enables to boot a system when the system files on the hard disk cannot be accessed

Troubleshooting a floppy disk drive fixes the drive
