Backup Disc Frequently
There is always a chance' of losing data when mass storage devices are accessed. There are
many causes in any computer system-a programming bug, operator error, power failure,
or hardware failure. In the case of flexible discs, another mode is possible-media failure
from contamination or wearout. YOUR ONLY PROTECTION AGAINST DATA LOSS IS
FREQUENT BACKUP OF DATA FILES.
Return Disc to Storage Envelope when Not in Use
This is the single most important thing to remember about handling a disc
because it prolongs disc life by protecting it from dust and scratches. Be-
tween uses discs should be stored upright in a dust free container. The box
that the discs are shipped in, or a similar container, is a good choice.
Operate in a Clean Environment
Airborne contaminants and particles accidentally dropped onto the disc
will cause the disc to wear out prematurely and may cause unreliable data
storage and retrieval operations. Some of the most common contaminants
are DUST, SMOKE, ASHES and ERASER PARTICLES. Chemical vapors
may also cause premature wearout.
