System and method for predicting disk failure

A computer implemented method for predicting failure of a disk in a digital storage system configured to store digital data, comprising:

• receiving user selection of one or more disk failure factors;
• receiving health status data obtained from monitoring the disk;
• identifying data included in the health status data that corresponds to the user selection of one or more disk failure factors;
• and
• determining a total failure value for the disk indicative of predicted risk of failure, using the identified data and based on a three dimensional matrix for determining bin failure weights wherein the matrix is defined by separate first, second and third two-dimensional tables, the matrix including includes a disk failure factor along a first axis, bins along a second axis and an umbrella failure factor along a third axis, wherein the first two-dimensional table includes bin failure weights entered corresponding to disk failure factors versus bins, the second two-dimensional table includes bin failure weights entered corresponding to bin weights using umbrella failure factors versus disk failure factors and the third two-dimensional table includes bin failure weights corresponding to umbrella factors versus bins, and wherein the total failure value is determined based on empirical data associated with the selected one or more disk failure factors.
