If you are really old, like over 40, and we're talking computer man-years here, which are about the same as dog years. (Other comparisions also likely to apply).
You might have seen or even used the forrunners to CD-rom, these were called diskettes. Computer programs or software used to be delivered on these small neat thingies, and yes programs used to be shipped separately before they all got bundled into Microsoft Office - praise to the monopoly!
Urgh! Got carried away again, cant walk a straight line, even less keep to the subject. But below you find some advice on how to keep those lil diskette thingies in working order and happy. Its really one amazing case of precognition since some of these recommendations even are valid today for the use and maintainence of CD and DVD disks!


1. Never leave diskettes in the disk drive, as data can leak out of the disk and corrode the inner mechanics of the drive. Diskettes should be rolled up and stored in pencil holders.

2. Diskettes should be cleaned and waxed once a week. Microscopic metal particles can be removed by waving a powerful magnet over the surface of the disk. Any stubborn matallic shavings can be removed with scouring powder and soap. When waxing the diskette, make sure the surface is even. This will allow the diskette to spin faster, resulting in better access time.

3. Do not fold diskettes unless they do not fit into the drive. "BIG" diskettes may be folded and used in "little" disk drives.

4. Never insert a diskette into the drive upside down. The data can fall off the surface of the disk and jam the intricate mechanics of the drive.

5. Diskettes cannot be backed up by running them through the xerox machine. If your data is going to need to be backed up, simply insert two diskettes into the drive. Whenever you update a document, the data will be written on both diskettes.

6. Diskettes should not be inserted or removed from the drive while the red light is flashing. Doing so could result in smeared or possibly unreadable text. Occasionally the red light remains flashing in what is known as a "hung" or "hooked" state. If your system is "hooking" you will probably need to insert a few coins before being allowed access to the slot.

7. If your diskette is full and you need more storage space, remove the disk from the drive and shake vigorously for 2 minutes. This will pack the data enough(Data Compression) to allow for more storage. Be sure to cover all the openings with scotch tape to prevent loss data.

8. Data access time can be greatly improved by cutting more holes in the diskette jacket. This will provide more simultaneous access point to the disk.

9. Diskettes may be used as coasters for beverage glasses, provided that they are properly waxed beforehand. Be sure to wipe the diskettes dry before using.

10. Never use scissors and glue to manual edit documents. The data is stored much too small for the naked eye, and you may end up with data from some other document stuck in the middle of your document. Razor blades and scotch tape may be used, however, provided the user is equipped with an electron microscope.

11. Periodically spray diskettes with insecticide to prevent system bugs from spreading.
