Unformatted text preview: 514-inch diskettes should not be bent and should not be applied
with any type of intense pressure.
6. To keep track of what information is stored on which floppy disk, and when was it
last used, the floppy disks should always be properly labeled.
7. Since magnetic particles tend to lose their charge with time, the data stored on floppy
disks may get damaged or lost after several months even if you take proper care of your
floppy disks. This problem is known as byte rot. To prevent data loss due to byte rot
problem, it is suggested that data stored on a disk should be refreshed (re-written) every
year. To do this, copy the contents of an entire floppy disk on to the hard disk of a
computer, and then copy them back on to the same floppy disk.
8. They should always be stored away from anything that has a magnetic charge or that
generates a magnetic field. For example, they should be kept away from magnets,
magnetic materials, and electric equipment.
9. They should always be stored in a place where it is not very hot or humid. Floppy
disks being made of thin plastic may get bad due to warping under extreme temperature
and humidity conditions.
10. Multiple disks should not be stacked on top of each other. They should be stored by
keeping them standing against their edge in specially designed plastic boxes to prevent
them from dust particles.
Floppy disks are very cheap as compared to other secondary storage devices. They are
also a convenient off-line storage medium for the small computer users. Hence diskettes are currently one of the most popular, inexpensive secondary storage medium used in
small computer systems.
Hard disks are the primary on-line secondary storage device for most computer systems
today. Unlike floppy disks, which are made of flexible plastic or mylar, hard disks are
made of rigid metal (frequently aluminium). The hard disk platters come in many sizes
ranging from 1 to 14-inch diameter.
Types of hard disks
Depending on how they are packaged, hard disks are normally categorized into the
