Abstract
One embodiment of the present invention provides a system that facilitates determining whether a disk drive is likely to fail. The system operates by monitoring at least three acoustic signals emitted from a two-dimensional array of disk drives and then comparing characteristics of each acoustic signal with baseline acoustic signals. These baseline acoustic signals reflect normal operation of the two-dimensional array of disk drives. If the acoustic signals differ by a predetermined amount from the baseline acoustic signals, the system identifies one or more disk drives in the two-dimensional array of disk drives that are likely to fail.
