/// Tested against Crystal Disk Info 5.3.1 and HD Tune Pro 3.5 on 15 Feb 2013.
/// Findings; I do not trust the individual smart register "OK" status reported back frm the drives.
/// I have tested faulty drives and they return an OK status on nearly all applications except HD Tune.
/// After further research I see HD Tune is checking specific attribute values against their thresholds
/// and and making a determination of their own (which is good) for whether the disk is in good condition or not.
/// I recommend whoever uses this code to do the same. For example -->
/// "Reallocated sector count" - the general threshold is 36, but even if 1 sector is reallocated I want to know about it and it should be flagged.
