Disk health (%) = Π (100% - (min(limit, attribute_value*Weight)))

where:

100% - an initial health of a disk;

Π - the product of minimums from (limit, attribute_value*Weight) - calculated for each critical

S.M.A.R.T. parameter;

Weight - a weight of each critical S.M.A.R.T. parameter (see a Table 1 below);

limit - a limit of each critical S.M.A.R.T. parameter (see a Table 1 below);

attribute_value - a current parameter's value.

Example:

1. Soft Read Error Rate = 30 (attribute value), weight = 1, limit = 20;

2. Spin Retry Count = 12(attribute value) , weight = 2, limit = 50.

So in this case the disk's health is calculated as the following:

Disk health =(100% – (min(30*1, 20))) * (100-min(12*2, 50))) = 80%*76%=60.8% ≈61%

The following table contains the health related (critical) S.M.A.R.T. attributes affecting the health

value with their weights and maximum limits.

Table 1.

Attribute ID S.M.A.R.T. attribute Weight Limit %

05 Reallocated Sectors Count 2 70

10 Spin Retry Count 2 50

184 End-to-End Error 1 50

196 Reallocation Event Count 1 40

197 Current Pending Sectors Count 1 40

198 Off-Line Uncorrectable Sectors Count 2 70

201 Soft Read Error Rate 1 20

Not critical parameters:

Other S.M.A.R.T. parameters, which have a predefined by manufacturer Threshold value, also affect

a disk's health: after decreasing below the threshold, this parameter subtracts 10% from the current

disk health. This means, when the current health is 90%, 9% will be subtracted.

A Table 2 shows non-critical S.M.A.R.T. parameters, that affect a disk health.
