Hard file Smart test

Use the Hard File Smart Test when the system management tool has detected a
hard file SMART alert.
The Smart test does the following:
v Interrogates IDE devices for support of the SMART instruction set.
v Issues a ENABLE SMART command to make sure SMART functionality is
active.
v Checks the SMART RETURN STATUS command to determine if any thresholds
have been exceeded.
If thresholds have been exceeded, an error message is shown, and the test fails. If
no SMART is supported by the drive, the test returns with "N/A".
