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.
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.
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.
what year?front or back? for the most part , all you do is remove wheel, remove caliper,then pull brake disk off if disk is a rear disk, the park brake is inside the disk and you will need to use a hammer to tap on disk to remove it. once the wheels are off there are only a couple of clips on some of the wheek studs to keep disk in place. the disk is actually held to vehicle with the wheel and lug nuts
Remove the calipers and the disk will pull right off
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).
You can't actually reformat when it's off. You'll need to power it up with a bootable CD or floppy disk which has the format command available. Besides, what you are formatting is the hard drive, not the computer. Or you can remove the hard drive from the computer in question and format it in another computer.
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.
No, you will not have to remove an external hard disk each time you turn your laptop off.
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
This is a start-up glitch. It is caused by having a floppy disk inside your computer when you turn it off and now your computer is trying to start from it. You may see the message 'Remove and strike any key to restart'. Otherwise eject the disk, press the Reset button (if there is no Reset button, press the power button to turn it off, wait 45 seconds, and turn on again) and log on as usual.
Remove the front tires and wheels. Remove the brake assembly. Tap on each rotor disk to loosen them. Slide the rotor disk off. Reverse the process to install the new rotor disk.
