Formatting prepares a floppy disk to store data
A floppy disk DRIVE can read, erase and save information on a floppy disk. The disk can't do it by himself.
When prompted to format the floppy disk, click NO. Especially if the disk has files that you wish to access. Formatting the disk erases EVERYTHING on the disk and starts the disk anew.

Start->My Computer->Right click on the floppy drive->Format. There are two kinds of formatting. The first one is "fast" which takes only couple seconds and good with new floppy disk or trusted used ones. The second one is "long" and includes the low level formatting and it can take couple minutes.

The best way to disable a floppy disk drive is to disable the floppy interface from the system BIOS. This should remove all traces of the floppy disk drive to the operating system. It is also easier to reverse should the disk need to be enabled again later,
The 3.5 floppy disk does have magnetism within them and for this reason, magnets destroying data on the floppy disk fueled the myth about magnets destroying your computer. If you buy a cheap magnet and put it near a floppy disk, the magnet will stick to it. After a few seconds, the information on that floppy disk will be destroyed and you will no longer be able to access the data.
