detecting new storage errors in the first or the second hard drive;

updating the first or the second error profile to include the new storage errors;

determining whether one of the addressable locations storing an encoded data slice of the set of encoded data slices has one of the new storage errors based on the updated first or second error profile;

when the encoded data slice is to be rebuilt, rebuilding the encoded data slice to produce a rebuilt encoded data slice; and

storing the rebuilt encoded data slice in a different addressable location than the one of the addressable locations.

determine whether one of the addressable locations storing an encoded data slice of the set of encoded data slices has one of the new storage errors based on the updated first or second error profile;

when the one of the addressable locations has one of the new storage errors, determine whether to rebuild the encoded data slice stored at the one of the addressable locations; and

the third memory section further stores operational instructions that, when read by the computing device, causes the computing device to:

when the encoded data slice is to be rebuilt, rebuild the encoded data slice to produce a rebuilt encoded data slice; and
