You can clean the heads of your diskette drives by using a commercially available
diskette-drive head-cleaning kit. These kits include diskettes pretreated with a
chemical solution to nonabrasively remove contaminants that accumulate on the
drive heads during normal operation.
If the kit does not contain instructions, insert one of the pretreated diskettes into a
diskette drive and turn on the system. After 20 or 30 seconds, remove the diskette
from the drive. Repeat this procedure for each diskette drive in the system.

This section discusses various environmental factors that can adversely affect system
performance and longevity.

Temperature extremes can cause a variety of problems, including premature aging
and failure of chips or mechanical failure of devices. Extreme temperature fluctuations
can cause chips to become loose in their sockets and can cause expansion and
contraction of disk drive platters, resulting in read or write data errors. When you
perform a low-level format operation on a hard-disk drive, it is important to ensure that
the drive’s surrounding temperature is at or near the temperature at which the drive
will be operated. Failure to do so can result in relocation of the tracks on the disk
platters.
To minimize the negative effects of temperature on system performance, follow these
guidelines:
‡
Ensure that the system is operated in an environment no colder than
10
°
Celsius (C) (50
°
Fahrenheit [F]) or hotter than 35
°
C (95
°
F).
‡
Ensure that the system has adequate ventilation. Do not place it within a
closed-in wall unit or on top of cloth material, which can act as insulation. Do not
place it where it will receive direct sunlight, particularly in the afternoon. Do not
place it next to a heat source of any kind, including heating vents during winter.
Adequate ventilation is particularly important at high altitudes. System
performance may not be optimum when the system is operating at high
temperatures as well as high altitudes.
‡
Make sure that all slots and openings on the system remain unobstructed,
especially the fan vent on the back of the system.
‡
Clean the system at regular intervals to avoid any buildup of dust and debris,
which can cause a system to overheat.
