Backing Up Data
Instruct users whom you
support to always make at least two copies of important data. If one copy
goes bad, instruct them to be careful not to do anything to the only good
copy before making a backup of it. Keeping extra copies of data disks is
the best insurance against lost data. Always be careful never to remove
disks from a drive while the drive light is on. Follow the exit procedure
in an application so that you close files properly. Store disks away from
heat, magnetic fields, and heavy dirt and dust. Occasionally, copy all
files from one disk to another, so that you have a newly copied disk that
is not fragmented. (Don’t use DISKCOPY; it just makes an exact copy of the
disk, fragments and all.) You can also use DEFRAG command to do the job
for you. Disks that are not badly fragmented are faster to read and write
to and, if data is damaged, are easier to recover.
Disposing Of Used
Equipment
As a PC technician, it
will often be your responsibility to dispose of used equipment and
consumables, including batteries, printer toner cartridges, and monitors.
The following table lists items and how to dispose of them. Manufacturer
documentation and local environmental regulators can also provide disposal
instructions or guidance. Monitors and power supplies can contain a charge
even after the devices are unplugged. To discharge the capacitors in
either device, place a screwdriver across a hot prong and the ground prong
of the electrical connections. To discharge the actual CRT in a monitor,
the monitor must be opened. Ask a technician trained to fix monitors to do
this for you.
A
material safety data sheet (MSDS) explains how to properly
handle substances such as chemical solvents. An MSDS includes information
such as physical data, toxicity, health effects, first aid, storage,
disposal, and spill procedures. It comes packaged with the chemical, or
you can order one from the manufacturer or find one on the Internet (see
www.ilpi.com/msds).
