The purpose of the plastic (or metal) shutter on a floppy disk is to keep dirt off of the magnetic medium when it is not being read.
Floppy disks are an old technology and very prone to corruption in a number of circumstances. If the disk is placed near any magnetic interference (speakers, monitor) if a disk gets to hot, or is exposed to light then data on the disk can become unreadable. It is very unlikely that data on a corrupt floppy disk can be recovered. It is generally considered that the use of floppy disks for day to day file storage is a thing of the past. It would be advised you remove any data you have on floppy disc to a new storage format such as flash memory.
Yes, information can be deleted off of a floppy disk by simply deleting the files or formatting the disk. Once the data is removed, it is not immediately visible but may still be recoverable using specialized software.
A file can be corrupted on a floppy disk any number of ways. Some of the more common ones are whenever you put the floppy disk near a magnet or some other source of ionized metal, if you try and pull the floppy disk out of the tray before the computer is done reading or writing it, or even if you somehow expose the inner part of the floppy disk to any type of electronic device (because of the electromagnetic waves that the electronic device gives off). As to how to retrieve the corrupted file, I don't know of any way to retrieve it.
I'm unable to show diagrams, but I can describe the components of a computer floppy disk for you. A computer floppy disk consists of a thin, circular, flexible plastic disk coated with magnetic material. It is enclosed in a square plastic casing with a metal slider to protect the disk surface. The disk is read and written to by a read/write head in a floppy disk drive, which moves along tracks on the disk to access data.
This likely means that: 1. You put the wrong disk in. 2. Your disk has become damaged in some way. 3. You are using a disk formatted by an unknown operating system (ie. a disk from a Mac inside Windows).
The biggest disadvantage is that it has very little storage capacity. The maximum storage capacity of a (last generation) floppy disk is around 240 megabytes. A USB stick, CD, or DVD-ROM can all hold much more than this. Secondly, fewer and fewer computer termnials are being manufactured with floppy disk drives, since they have been replaced by other storage methods. This means it is hard to get your data off the disk. Thirdly, floppy disks are more easily corruptible than other methods of data storage.
Connecting a floppy Drive in a Desktop ComputerYou should connect the 4-Pin 12 Volt non-molex Connector from the power supply to the power input of the Floppy Disk Drive, also the IDE ribbon cable from the FDD output on the Main-board to the FDD input on the Floppy Disk Drive, with the pink stripe on the outside of the FDD Input & Output sockets, it is important to make sure you are grounded to the case whilst doing this with the PC Power Cord plugged in but switched off
Any Airprint-compatible printer connected to the same wifi network as the iPad can print from the iPad with any app that has printing support.
"Not really. A USB drive is more like a CD or floppy disk, but is made to look like another drive on your computer when it's plugged in, because information can be added and removed from it at will" "A USB drive is similar to your hard drive in that you can freely move information on and off of it, but in reality, it's much closer to a floppy disk."
There are a number of differences between CD and floppy discs. Floppy discs are magnetic and use magnetism to store data, CD drives are optical and read pits in a reflective surface using a laser. CD's have a much higher data density than floppy discs. CD's are a much higher capacity and can be read at much higher speeds than floppy discs.
The old 5.25 inch disks had a notch that is covered/uncoverd for write protection. The not so floppy 3.5 inch disks have a little plastic slide that did the same thing. Software disks in that format might have a notch that can be covered with tape.
