Reading Floppy Disk on Dell Intel Core I3
Floppy disk bulldoze is a storage device, used to store data in floppy disks. The capacity of floppy disks to store information is low every bit compared to hard disk drive or SSD. The FDD is not used in latest desktop abode computers merely information technology is still used in some older industrial machines.
Sizes and Chapters of Floppy Disks used in FDDs
The floppy disk drive comes in two sizes with varying capacities.
- 5″ Floppy Deejay Drive. Latest of the two sizes, this FDD supports the floppy disks of capacities 720Kb and 1.44Mb
- 5.2″ Floppy Disk Drive. The five.25 Inches of FDD is the oldest model of the two and the floppy disks of 360Kb and i.22Mb capacities can be used .
Floppy Disk Bulldoze Connection in Computer
- 34-pin male person connector on Motherboard. As yous tin meet in the figure below, there is a 34 pin male connector on the motherboard which is assigned for floppy deejay drive connection.
- FDD interface Cable. A 34-pivot cable is required for connectivity to the floppy deejay drive. With one cablevision you lot tin connect ii floppy disk drives. The Drive that connects at the twisted end becomes A-Bulldoze and the drive at the other end turns into B-Drive.
"TIP:The red wire is the No.1 wire and make sure to connect it to the No.1 of connectors on both FDD and motherboard"
"Warning: If the LED on the front side of FDD glows permanently it means the cable is connected in contrary direction."
- Ability Connector. The power is supplied to FDD on a four-pin male connector equally shown in the figure.
Motors used in Floppy Disk Drive
- Spindle Motor. It is used for media rotation that is to rotate the floppy disk at the speed of 360 RPM(rotation per infinitesimal) for 1.22 Mb floppies and at the speed of 300 RPM for 1.44Mb.
- Stepper Motor. There are ii heads to read media. The media(floppy deejay) rests between Head 0 and Head i. The stepper motor is used for the move of the head. The stepper motor needs step pulse signal and direction signal which it receives from FDD-controller flake on the motherboard.
- Head 0. Equally yous tin can see in the picture, this head is stationary and cannot move and is fixed on the lower portion of FDD.
- Head 1. Out of the two heads, it is Head ane that moves forrard and backwards and is mounted on the upper portion of FDD.
Floppy Disk Geometry Table
| Capacity | Sides | Tracks | Sectors / Rails | Bytes / Sector | Tracks/Inch(TPI) |
| 360 Kb | 2 | xl | 9 | 512 | 48 |
| 1.2 Mb | 2 | 80 | 15 | 512 | 96 |
| 720 Kb | 2 | 80 | nine | 512 | 135 |
| one.44 Mb | two | lxxx | eighteen | 512 | 135 |
Calculating floppy disk capacity
Annotation: 360 bytes=0.3 Kbytes
Calculation of deejay capacity ( in Kbytes)= No. of Sides x No. of Tracks x Sectors/track x Kbytes/sector
Example- 720Kb: 2 x 80 10 nine x 0.512=720Kb (values taken from to a higher place Table)
Different types of sensors in Floppy Disk Drive
- Media Sensor. Media sensor is used to discover whether the floppy is inside the drive or out. For earlier disks size of 5.25 Inches, this sensor is of optical type and the floppy disks with 3.5 inches of size, the same sensor works on magnetic principle.
- Runway 0 Sensor.Whenever the head touches the first track that is track 0, this optical sensor gets activated.
- Alphabetize Hole Sensor. If the light manages to get passed through this small hole, it means the head has moved to the next track. The Index Hole sensor then the status signal to the electronics controller flake.
- Write Protect Sensor. Write Sensor is used to enable or disable writing the data on floppy. If the sensor is ON, you can write data and prevents writing if this sensor is in Off position.
