1. A method of performing reliability analysis in disk drives in an installation base comprising the steps of:

  • recording identification information about each disk drive in a family of disk drives in the installation base;

    recording error codes that are generated by the disk drives operating in the installation base;

    creating a reliability database including mapping each recorded error code with a particular drive family;

    adding to said reliability database further information from a drive manufacturer about failure mechanisms associated with one or more error codes; and

    retrieving one or more error codes reported for a disk drive family during a time period, and matching the retrieved error codes with one or more failure mechanisms for that drive family.
