31 : * - Disks that are predicted to fail by BackBlaze are removed before
32 : * they really fail, not counting as a failure.
33 : *
34 : * The following tables are computed using the data from 2014-02-14 to
35 : * 2014-12-31 because it's the period when more SMART attributes were gathered.
36 : *
37 : * In this period there are 47322 disks seen, with 1988 removed because failed,
38 : * and with 4121 removed because predicted to fail.
