Abstract
It is estimated that over 90% of all new information produced
in the world is being stored on magnetic media, most of it on
hard disk drives. Despite their importance, there is relatively
little published work on the failure patterns of disk drives, and
the key factors that affect their lifetime. Most available data
are either based on extrapolation from accelerated aging experiments
or from relatively modest sized field studies. Moreover,
larger population studies rarely have the infrastructure in place
to collect health signals from components in operation, which
is critical information for detailed failure analysis.
We present data collected......
