you need to "write protect" your floppy disk.if you turn the floppy disk over you will see a little tab on the lower right hand corner,push this tab down until you can see the hole through it.your disk is now write protected and cannot be overwritten.
Set the write protect tab (or tape over the write protect notch).
A standard floppy disk can hold a maximum of 1.44MB. This is comprised of 720kb of data on both sides of the platter. Some floppy disk drives can read disks of upto 2.88MB in capacity.

The head(s) in floppy drives make physical contact with the floppy disk surface, while the heads in hard disk drives fly over the hard disk surface on a cushion of air created by the platter rotation speed. All other features of the devices are similar.
The function of a floppy disk drive is to provide a means of writing/reading data on/from floppy disks in an industry standardized method. Floppy Disks were invented as an improved means for storing/transporting data on/from computers. The universality and standardization of disk storage technologies was important to the personal computer industry. By standardizing these complex technologies, computer manufacturers were able to, over time, inexpensively source drives and disks, thus reducing the cost of the computer systems. This made PC's more affordable for everyon
The "A" drive is normally still considered to be a 3.5 inch floppy disk drive. Each removal "floppy disk" has a small square hole in the edge opposite the site that entered the drive first. In this hole is a small plastic gate or door which if it covers the hole makes it write capable and if its moved to reveal the hole it makes it "write protected" meaning that you cannot accidentally over write the contents. 5.5 inch disks are also make in the same way.
Modern 3.5" floppy disks were/are double sided. Earlier 5.25" floppy disks started out single sided but you could cut out a read only slot and flip them over and use both sides, no guarantees though. Even earlier 8" floppy disks were also single sided but could likewise be cut and flipped over. This is from my own experience not from research.
The highest density 8 inch floppy can hold a little over 1.2 MB. The smallest density 8 inch floppy can hold 80 KB.
no something worse will happen the disck will get out of control and breack
The most usual occurrence of this when the data cable is plugged in upside down onto the floppy disk. Just unplug is and flip it over. Nothing has been hurt. Just power down, flip the data cable and power up again. Otherwise, something is wrong with the floppy and it should be replaced.
For 5.25" and 8.00" disks there are "write notches" on the jacket of the disk. They are on the opposite end of the jacket from the read slot (where you can see the surface of the disk). Single-sided media will have one write notch and double-sided media will have two. To write protect a disk of this type, simply fold a piece of sturdy tape (like masking tape) over these notches and the disk will be protected. Most discs come with adhesive tabs for this purpose. For 3.5" floppy disks, there are "write protect tabs" built into the disk shell. These tabs are located in the corners of the case opposite the shutter-end. By moving the tab to the "open" position (you can see through the shell) you write protect the disk. The only exception to this is "OEM" floppy disks made specifically for software companies. These floppies were manufactured without the write protect tabs so they couldn't be written to after initial production. This can be defeated by simply taping over the tab area with opaque tape.
