Generally, I'm looking for a source of information about what the heck all the stuff SMART tools produce.

More specific, I got output from long test in SMART tools that includes this:

Code:
Read SMART Thresholds failed: scsi error badly formed scsi parameters

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED
Afterward there is a lot of "stuff". So how do I interpret to decide whether to put the drive in use or chuck it?

I've done some searching an found no info about the "scsi error badly formed scsi parameters".

As for general interpretation of the entire output, I've searched and found some treatise on the subject, but am interested if others have preferred sources.
