What else may decrease a disk's health?
When a disk is monitored using a custom script:
 exit code is 0 : Health = (disk health calculated by S.M.A.R.T.) * 100%
 exit code is 1 (warning) : Health = (disk health calculated by S.M.A.R.T.) * 50%
 exit code is 2+ : Health = 0%
Factors not affecting a disk health
 Decreasing value of a non-critical parameter does not affect the disk health till it is above a
threshold, specified by the disk's manufacturer;
 Event log entries also do not change the overall disk health, but still can generate Warnings or
Errors.
3.2.5 Using custom script
If any of your hard drives does not support S.M.A.R.T. for monitoring, you can create a custom script.
Each hard disk needs a separate custom script. On an Options (p. 21) page you may select a required
script for a drive in a Disk monitoring (p. 24) section.
The executable's output will be returned through the exit code and recorded to the respective log
entry.
Executed custom script provides a report about disk status:
0 - there are no errors and warnings, the disk is healthy;
