1. A method for execution by a processing module to extend life of a set of hard drives for reliably storing data, the method comprises:

  • determining a first error profile for a first hard drive of the set of hard drives, wherein the first error profile includes at least one of detected storage errors and predicted storage errors for the first hard drive;

    determining a second error profile for a second hard drive of the set of hard drives;

    determining a dispersal configuration based on the first and second error profiles;

    encoding a data segment of the data in accordance with error coding dispersal storage function parameters to produce a set of encoded data slices;

    defining addressable storage sectors within the first and second hard drives based on the dispersal configuration and on the first and second error profiles to produce a set of addressable storage sectors; and

    storing encoded data slices of the set of encoded data slices at addressable locations in corresponding addressable storage sectors of the set of addressable storage sectors.
